C Programming - Learn Computer Programming With C Language

Install dev c++ and set up an integrated development environment, learn to use a text editor and compiler, create a project, write a basic C program, and compile and run.

Explore the basic C program structure by including stdio, writing the main function, using printf to output to the console, returning 0, and commenting code to explain logic.

Use basic stdio functions like printf and scanf to read from the keyboard and print to the console in C, handling integers, characters, and strings with formatted output.

learn to write a simple c program that reads two integers, performs addition, subtraction, multiplication, and division, stores results in variables, and prints them with printf format specifiers.

Learn to create a basic C program that collects user name, age, mobile number, and salary, stores strings in arrays with size limits, and displays details with format specifiers.

Open a codeblocks ide project to run C and C++ programs, print hello world, and understand compiling, warnings, and the difference between errors and warnings.

Explore the core C operators, including arithmetic, increment/decrement, relational, and logical, and see how they drive decisions and loops, including a simple login check.

Explore how if and else statements control flow in the C programming language by evaluating conditions, comparing marks, and executing corresponding blocks or outputs.

Learn to build a login system in C with nested if-else statements to verify a username and password using a string comparison that returns zero when equal.

Practice building a sign-up and login flow in C using a switch statement with character options, handling username, password, and age, and storing credentials in a simple database.

Learn to compute the sum of digits using a while loop and modulus, extracting each digit and accumulating the total for numbers beyond 10 digits.

Explore the for loop in C, compare it with while loops, and learn its syntax: initialization, condition, and increment, with examples printing stars and numbers in ascending and descending order.

Create a c program using a nested for loop to print a six row star pattern, with outer and inner loops guiding the design.

Develop a simple cube pattern in C programming using nested for loops, printing hashes with inner and outer loops and managing line breaks.

Explore the do-while loop in C and its syntax. See how the body executes at least once before the condition is checked, with examples printing numbers.

Explain arrays in c, including one- and two-dimensional arrays, with declarations, initialization, and accessing elements by index, plus memory considerations and for loops to print all elements.

Learn to store five names in a C array of strings by using characters, initializing them, and printing each name with a for loop.

Learn to perform addition of two matrices in C by accepting two matrices with the same number of rows and columns, and display the resulting matrix.

Implement a five by five multiplication table in C by computing with an array named product using nested for loops and printing a spaced matrix separated by dashes.

Explore function basics in C, covering parameters and return types, declaration versus definition, and function calls in main, with an example of adding two numbers and displaying the result.

Learn how to reverse a number in C by taking input, using a while loop and a reverse function, and computing digits with modulus and division by 10.

Learn how a function executes in a C program, from declaration or automatic declaration by the compiler to calling the function and returning an integer value.

Explore how to use the math.h library in C to perform square roots, powers, sine, and absolute value calculations, with examples using printf formatting for floating point numbers.

Explore the ctype.h library in C, learn to include the header, and use isdigit, isalpha, and isspace to classify characters, then convert between uppercase and lowercase as shown.

Learn how strings are represented in C as one- and two-dimensional character arrays, how to declare and initialize them, and how to print and read them using printf and puts.

Explore the C string library with essential functions for length, reverse, compare, copy, concatenate, and case conversion using tolower and toupper, illustrated with sample code.

Enter a string and learn to convert each character between upper and lower case in C programming, using the string length concept.

the lecture covers dynamic memory allocation in c, using malloc, calloc, and realloc to allocate, reallocate, and manage memory for a paragraph of characters, with memory freeing.

Explore unions in C programming, compare them with structures, and learn how a union shares memory among its members, sizing to the largest member.

Explore common hacking attacks such as brute force attacks, phishing, and malware, and understand how social engineering enables intrusions. Then study encryption and decryption techniques.

Explore encryption concepts, including plaintext, ciphertext, encryption and decryption, and the cipher algorithm, learn their purpose for privacy, and begin building a secure application from scratch.

Explore how the Caesar cipher, a substitution cipher, encrypts and decrypts text with a key of three using ASCII shifts.

Learn to build a simple C program that simulates username and password verification by prompting user input and comparing it to stored credentials, without a database.

Validate a username and password via string comparison, handle login success or failure, and implement a 1–3 option menu with a switch statement for encryption, decryption, and exit.

This lecture teaches building a C encryption program by defining an encryption structure to store message and key, then encrypting by adding the key to each character and preparing decryption.

Execute the decryption phase by applying a key to ciphertext, display the decrypted message, update the user interface, and verify functionality with compilation and standard library usage.

Build a C encryption app with a simple user interface, authenticating the user and encrypting or decrypting text using a numeric key via a switch-driven menu.
