Description

The fastest, easiest way to learn to program C on a Mac or Windows. This course will teach you to program the C language from the ground up. You will learn everything from the very fundamentals of programming right through to the complexities of pointers, addresses and File IO. Maybe you've tried to master C before but failed. Or maybe you are new to C or new to programming. If so, this is the course for you!

C is one of the most important of all programming languages. It is used to program desktop applications, compilers, tools and utilities and even hardware devices. The C language is fast and efficient – but it can be hard to learn. Unless you use this course. This course begins with a gentle introduction to C but quickly moves on to explain some of its most confusing features: everything from C's 'scoping' rules to the curious connection between arrays and memory addresses. By the end of the course you will have a deep understanding both of the C language itself and also of the underlying 'architecture' of your computer.

What you will learn:

  • The fundamentals of programming – from the ground up
  • How to program on a Mac or on Windows
  • The nitty-gritty details of the C language
  • Advanced topics such as memory allocation, the stack and heap, and binary file IO

Who should take the course

  • Beginners – if you've never coded before, you can learn C step by step
  • Programmers switching to C from some other language such as Java, Ruby or Python
  • Cross-platform developers – there are C compilers for all major operating systems
  • Anyone who needs to program C++ or Objective-C. The C language is the place to start
Who is the target audience?
  • Newcomers to programming
  • Programmers of other languages who want a fast way into C
  • Anyone who needs to master C as a basis for using C++ or Objective-C

In this course I will generally use the free CodeLite C editor which is available for OS X, Windows and Linux. This video shows how to get CodeLite installed on your computer.

Install CodeLite (Windows or Mac)
02:12

If you are using a Mac you may need to download some additional tools in order that an editor such as CodeLite is able to find a compiler to build and run your programs.

03:18

Let’s take a quick look at the features of the CodeLite editor – from syntax colouring to keyboard shortcuts. CodeLite makes light work of creating C projects on Windows and OS X.

Maybe you are already use the NetBeans IDE for Java programming. Or maybe you'd just like to use NetBeans as your C environment. Here I explain how to get up and running.

Programming C with NetBeans
02:12

There are various ways of importing source code into NetBeans. Here I show a simple way of creating a NetBeans C project using the files from one of my sample projects.

Importing Projects Into NetBeans
05:55

You don't need to use an IDE at all. If you are having problems installing an IDE or if you'd prefer to use a simple text editor, you can do so – and compile your programs in a System or Terminal window.

09:39

If you are using Windows, Microsoft’s Visual Studio (even the free edition) may be used to create C projects. Here I explain how to do that.

C programming basics
6 Lectures 27:05

Here I take a look at a simple program that just displays “Hello world” and discover that even a few lines of C code illustrate a number of important features of the C language.

Preview 06:06

Some “Hello world” programs are more complex than others. Here I look at a program that takes some data as ‘arguments’ and returns a value.

Arguments and return values
04:10

Here I explain how to pass arguments from the commandline (or Terminal) to your program.

Passing commandline arguments to your program
05:13

If you don’t know how to open a command window on Windows or the Terminal on OS X and use it to run your programs, this lesson explains all.

04:35

The printf() function lets you display the output from your program. It’s a very useful function but must be used with care – as I explain here.

05:17

You can document your code with comments that are ignored by the compiler. Here I explain two types of comment.

Variables, constants and types
5 Lectures 22:14

Variables are identifiers whose values may vary during the running of your program. This video explains the basics of variables and their types in C.

Variables and types
03:47

You may do calculations with both full numbers – integers – and fractional numbers – floating points. But be careful: the end results may not be what you expect!

Integers and floating point numbers
04:32

If you want to create identifiers to store values that are not expected to change during the execution of a program, you can #define them.

Constants
03:42

Identifiers that are created using #define are often used as ‘constants’ – but, in fact, there is an alternative – using the keyword ‘const’. Here I explain the difference.

More about constants
04:44

What should you call your variables and constants? Here I consider some of the naming conventions adopted by man C programmers.

Operators, tests and user input
9 Lectures 51:16

There are two ‘equals’ operators in C – one uses a single equals sign to assign a value to a variable. Another uses two equals signs to test for equality. Here I explain the difference.

Operators – equality and assignment
02:47

You will frequently need to make comparisons between one value and some other value. C has a number of ‘relational operators’ to help you do this.

Operators – tests and comparisons
03:31

Some assignment operators in C perform a calculation prior to assigning the result to a variable. These are called ‘compound assignment operators’.

Compound assignment operators
03:35

You can use ++ and – to add and subtract 1 from a variable. But be careful – you can put these operators either before or after a variable and the position matters!

Increment and decrement operators
03:52

There are times when you need to take different actions according to some test condition. Here I explain how to use if..else tests.

if and else tests
06:32

It may seem easy to get input with gets() but this may cause problems. The fgets() function is a safer alternative – but that too may cause its own problems, as I explain here.

Problems with gets() and fgets()
07:46

Sometimes you may have more data lurking in the dark corners of your computer’s than you are expecting. Here I explain some of the mysteries of buffers and why they need to be flushed.

Input, buffers and flushing
09:32

Here I look at two possible ways of writing a function that safely reads in characters entered at the command prompt and also flushes any unneeded characters from the buffer.

My own line-reading function
08:41

If you need to chain together conditions when making tests, you need to use C’s ‘logical operators’.

Functions, arguments and switch
4 Lectures 27:56

We’ve used functions from the very start of this course. In this lesson I explain more about what functions are and how they really work.

Functions
09:26

You can pass data to functions are arguments that are assigned to ‘named parameters’. Here I explain the nitty-gritty details of arguments .

Arguments
06:19

There may be times when you need to take many different possible actions depending on the value of some variable. The switch statement can help out.

Switch statements
06:55

In this lesson I look at more examples of switch statements, including some options that are only available with some C compilers.

Switch statements in more detail

Arrays, loops and break
7 Lectures 35:07

Arrays are sequential collections. You can use arrays to store lists of chars, ints and other types of data. Here I explain the fundamentals.

Arrays
03:26

You can add elements to an array at the same time the array is declared. Here I show how to do this and I also explain how the results of calculations may change according to the ‘precedence’ of operators.

Initializing arrays
06:36

Sometimes you might want to run some code not for a predetermined number of times but for just as long as some condition remains true. You can use a ‘while’ loop to do this.

‘while’ loops
04:26

In some circumstances the code in a ‘while’ may never be run. If you want to ensure that your code is always run at least once, use a ‘do..while’ loop.

‘do..while’ loops
02:53

Sometimes it is useful to break out of a loop even if the loop’s test condition is not false. Here I explain how to use break in a ‘while’ or ‘for’ loop.

break
05:19

Sometimes you may want to break from a loop once but then continue running the loop afterwards. Here I explain the difference between ‘break’ and ‘continue’.

break and continue
05:18

Arrays can have multiple dimensions to let you star arrays inside arrays. Here I explain how you can think of a two-dimensional array as being a bit like a spreadsheet with intersecting rows and columns.

Multidimensional arrays

Strings, chars and pointers
8 Lectures 44:19

In order to understand strings in C you need to understand how computer memory can be represented by ‘addresses’ and how pointer variables can refer to those addresses.

Strings, pointers and addresses
03:50

Many programming languages have a dedicated string data-type. Here we revise the essential features of C strings and explain the significance of its lack of a string type.

Null-terminated strings
04:11

At first sight there may seem to be no difference between an array of chars such as char str[] and a char-pointer such as char *str. In fact the difference is profound and important.

Char arrays and pointers
07:49

Here I look at some more examples of using arrays and pointers and consider why you can assign to a pointer variable but not to an array name.

Arrays, pointers and assignment
06:06

How do you return strings from functions And we also look at the importance of understanding the ‘stack and ‘heap’ in your computer’s memory.

Strings and functions, stack and heap
06:58

C compilers come with ready-to-use string functions. Here I look at some of the traditional functions as well as some more modern alternatives.

String functions
09:39

There are also functions that let you analyse individual characters in order to determine to which category each char belongs.

char functions
03:27

What is the difference between ‘x’ and “x”? They may look almost identical but, in fact, they are completely different – as this lesson explains.

Structs, enums, header files and scope
9 Lectures 47:20

Let’s imagine that you want to create a catalogue of your CD collection in which each record contains a name, the artist name, the number of tacks and a user rating. Here I explain how structs can help.

structs
05:44

C lets you define your own named types. This makes it possible to create type names for everything from an int to a string to a custom record or struct.

Preview 03:10

Enums let you created groups of named constants that can help to document your code. Here I explain their value – and their limitations.

Enums
07:46

What is the purpose of the ‘.h’ header files that most C programs include? Here I explain why header files are useful and how they are used during the compilation of your programs.

Header files
08:12

Here I look at an example of a header file that provides access to a set of functions and constants that I have written.

A custom header file
02:26

‘Scope’ defines the visibility of functions and variables to your code. Here I explain local and global scope and look at the scoping of two variables with the same name.

Scope
04:15

What is the scope of functions declared in external files – that is, functions that are in different files but the same project?

Scope and external files
02:45

Sometimes you may want your functions to be ‘private’ – hidden from code in other files. Here I explain how static functions can do this, and I also explain static variables.

Static functions and variables
06:03

To understand better how the compiler and linker work and how the compiler may rely on information from header files, try compiling your projects at the system prompt.

File-handling
5 Lectures 19:20

In this step we look at file operations. In this video I explain how to open and close disk files in order to save and load data to and from them.

Opening and closing files
03:11

When you open a file you can use a short string to indicate the file ‘mode’. A file mode may make a file available for reading, writing or appending in text or binary format.

File modes
02:44

Here I go through the code in a sample project to show how text can be saved to and loaded from a file, how the file contents can be erased and how the file itself can be deleted.

Reading and writing a text file
05:05

Once you’ve opened a text file you may want to do something with the text it contains. In this video I show how to count the number of lines in a file.

Counting lines in a text file
04:17

Now you know how to read and write text files you can write programs to process the text in a variety of ways – for example, to search for words in a file or encrypt its contents.

Binary files and memory allocation
8 Lectures 42:01

Not all files contain plain text. Some files may contain binary data – for example, if I were to save a CD database to disk, the data stored in each CD struct would have a binary representation. This video explains the basics.

Binary files
05:30

Sometimes you need to allocate memory dynamically. But once you’ve finished with that memory you need to free it. This lesson gives an example of code that does this.

Allocating and freeing memory
05:54

The C language provides a number of standard data types. Sometimes it is useful to treat one type as another type. In this lesson I explain the hows and whys of ‘type-casting’.

Types and type casts
07:48

The final project in this course creates a database of CD structs that are saved in a binary file on disk. This video introduces you to this project.

Creating a CD database
02:59

Here I explain how to save a collection of records (structs) into a binary data file and how to calculate the number of records stored before allocating memory when reading them in again.

Saving and loading records in a binary file
07:17

Here I explain how to create a new CD struct in memory and then append its data to the end of an existing binary file storing CD records.

Adding records to a binary file
04:54

Finally I show an example of how to find a record in a binary file and modify the data it contains. You can use the sample program as a basis for your own data-saving application.
