C in Depth: The Complete C Programming Guide for Beginners

Explore C keywords, and learn how to declare and use variables and constants, choose data types, and apply control statements such as if, else, switch, and loops.

Explore the basic C data types and derived types such as arrays, pointers, structs, and unions, plus void, signed and unsigned literals, and their sizes and value ranges.

Define constants in c using #define or the const keyword to hold fixed, unmodifiable values. Explore literals such as integers, characters, and strings and demonstrate their display on the console.

Learn to use printf and scanf in C to read two numbers from the user and print the result, including how to include stdio.h and use format specifiers.

Examine C comments—single-line and multi-line—and how the compiler ignores them, then overview arithmetic, relational, logical, bitwise, and assignment operators, plus conditional and size-of operators and pointers.

Explore operator examples in C for beginners, covering arithmetic, relational, logical, and bitwise operators, assignment, if statements, and the size operator with console output.

Explore how to compare two numbers using the conditional (ternary) operator, read input, and display the greater value, while illustrating assignment, arithmetic, and relational operations in C.

Explore the if statement in C, including syntax, condition evaluation, and basic if-else logic. Learn to read user input, test even numbers with modulus, and print results to the console.

Learn how the if-else statement in C uses a boolean expression to execute code when the condition is true and to branch to alternative code when it is false.

Learn how the if and else if ladder handles multiple conditions to assign grades from marks and print the corresponding grade in C programming.

This lecture explains the switch statement in C, showing how an expression matches case values in a calculator example with addition, subtraction, multiplication, and division, using break and a default.

This lecture demonstrates a switch statement driven calculator: take two numbers, present four operations (addition, subtraction, multiplication, division), handle a default case, and validate user input.

Write a C program that reads a number, tests if it is divisible by two, and prints whether it is even or odd.

Explore how C loops execute statements multiple times to minimize code, using for, while, and do while with initialization, condition, and increment; view a 1 to 10 printing example.

Execute a nested for loop to print a four by four star pattern on the console, detailing outer and inner loops, and controlling line breaks for each row.

Explore the while loop in C, including its syntax, condition evaluation, and how it repeats while the condition is true, with a break and an example printing 1 to 10.

Explore the do while loop in C, learning how the body executes at least once before checking the condition, and compare it to while and for loops with practical examples.

Learn to write a C program that calculates the factorial of a user-entered number using a for loop and repeated multiplication, producing results like 5 factorial equals 120.

Explore function basics in C: learn about library and user-defined functions, function prototypes, definitions, calling, parameters, and void or return values.

Define and call a parameterized C function to add two numbers, return the sum, and reuse the function, while distinguishing function names for addition and subtraction.

Compare call by value and call by reference in C, detailing how actual arguments are copied or addresses are passed, and how formal arguments reside in separate memory locations.

Demonstrates call by reference in C, showing how passing a pointer lets a function modify variables in main and reflect changes in memory.

Illustrates recursion in C by defining a function that calls itself to compute factorial, explaining the recursive function, its call within itself, and the use of return statements.

Learn how arrays in C store multiple values of the same type, initialize and access elements by index, and display student marks using loops.

Explore array basics in C by defining an array, initializing five values, and using a for loop to print elements to the console, with optional user input to store values.

Explore how a two dimensional array stores and retrieves values, using nested loops to input and display elements in rows and columns with 0-based indexing.

Learn how to pass an array to a function in C, define a display function, and call it with the array's address to print its five elements on the console.

Explains pointer to a pointer, showing how a pointer stores a memory address, how a second pointer stores that pointer, and how to display values via dereferencing.

Learn pointer arithmetic in C by incrementing pointers and observing how addresses change by the pointed type’s size, including 64-bit system effects on memory and byte differences.

Explore dynamic memory allocation in C, contrasting static memory with heap memory using malloc and free. Allocate runtime blocks, store elements, and display the computed sum.

Illustrate strings in C by contrasting string literals with character arrays, explain null termination, and show how to declare, modify, and print strings using the standard library.

Learn how to read and print strings in C using gets and puts. See a simple example that prompts for a name, stores input, and displays it on the console.

Learn to use the C string library to measure, copy, concatenate, compare, reverse, and transform case of strings with strlen, strcpy, strcat, strcmp, strrev, strlwr, and strupr.

Explore how to use C math functions from the math.h library, including ceil, floor, sqrt, and pow, with practical examples and code snippets.

Learn to define a structure in C, assign values to its members, and retrieve them, using struct and string copy to manage fields like name and marks for multiple students.

Explore how file handling in C stores data permanently by opening a file, writing with write mode, and closing it; see a practical example.

Learn how to read data from a file in C by declaring a storage variable, opening the file, scanning input until end of file, and printing data to the console.

Learn how the C preprocessor handles macros and directives like #include for header files, #define, #undef, #if, #ifdef, and #pragma to tailor code before compilation, with practical examples.
