The Complete C Programming Course for Beginners

Learn the basic structure of a C program, including the header file and main function, with variable declarations and a print statement, returning an integer to signal success.

Write a hello world program in C by including stdio.h, using main and printf to print hello world to the screen, and returning 0 to signal successful execution.

Learn how the #include line brings in standard input/output by copying header code into your file, enabling the print function; without the include, you cannot use this print function.

Learn how to print the value of a variable in C using printf with format specifiers for char, int, float, and double.

Explore C datatypes with examples, covering character and integer ranges, float and double storage, memory, overflow, and format specifiers like %f and %lf.

Define constants as fixed values that cannot change during execution, such as integers, floats, characters, and strings, and show how to declare them with the const keyword.

Demonstrate how characters are stored in memory as ASCII values, using 8-bit bytes. Show how C prints them with %c by converting binary to decimal.

Explains how 32-bit integers are stored in memory using binary, with the most significant bit indicating sign, and introduces two's complement for representing and printing negative values.

Explore how IEEE-754 floating point numbers are stored in memory using sign, exponent, and mantissa. Learn the differences between single precision (32-bit) and double precision (64-bit) formats.

Explains how a 32-bit floating point number is stored in memory using sign, exponent, and mantissa, with bias 127, and how 10.75 is normalized and printed.

Learn how signed and unsigned integers differ, including their minimum and maximum values, and view their 32-bit binary representations using the sign bit and two complement.

Explore the three types of operators in C, including unary operators (plus, increment, decrement), binary operators (assignment and two-operand operators), and the ternary conditional operator with examples.

Explain assignment operator in c, showing how the equals sign assigns a value to a variable and requires type matching; demonstrate shorthand forms like +=, -=, *=, /=, and %=.

Learn how arithmetic operators work in C, covering addition, subtraction, multiplication, division, and modulus with symbolic forms and example expressions like 4+2, 4*2, and 4%2.

Learn how the preprocessor uses the #include directive to copy code from a header file into your source. Include the header to access printf for standard input and output.

Discover how to get input from the user in C with scanf, print results with printf, and use the address operator & for single or multiple variables.

Explore how the newline metacharacter and the backslash work in C, using a hello world example to print across lines and format output.

Explore the three logical operators in C—or, and, and not—covering unary and binary behavior, boolean values as 1 for true and 0 for false, and short-circuit notes.

Learn how operator precedence and associativity determine the order of evaluation in expressions, with parentheses highest, then multiplication and division, and left-to-right associativity for equal-precedence operators.

Master if and else statements in C by understanding the syntax with parentheses, expressions, and body, then execute the appropriate block on true or false, and explore switch with default.

Master nested if...else statements in C, learning how to place an if inside another and evaluate expressions to control nested blocks.

The lecture shows a C program to check if a number is even or odd with if else statement. It reads input with scanf, prints with printf, and returns 0.

Master the switch statement in C, using case labels, break, and default to test a variable's value with equality checks among integral types and multiple cases.

Implement a C program using a switch statement to check if a number is even or odd by computing num % 2 and printing 'even' or 'odd'.

Learn to find the maximum of two integers in C by comparing two inputs with an if statement and printing the larger value.

Learn to find the maximum of three integers using conditional comparisons and printf in C, with step-by-step logic to declare variables and print the result.

Learn to find the maximum of three integers using a nested ternary operator in C, with a practical code example and output demonstration.

Explore loops in C programming, learning how to repeat a block of code efficiently with for, while, and do-while loops, illustrated by printing good night multiple times.

Learn how break and continue statements control loop flow in C programming, terminating the loop or skipping the current iteration to advance to the next one.

Explore infinite loops in the C programming language through examples of for, while, and do-while loops, showing how they print Hello World forever.

Learn to write a simple C program that repeatedly prompts for a positive integer until one is entered, then prints the valid number.

Learn to compute the sum of integers from one to n in C using for, while, and do-while loops. Read input, accumulate with sum += i, and print the result.

Learn to compute the factorial of an input integer in C using a for loop. Multiply from 1 to n, then print the result.

Compute the greatest common divisor of two integers. Iterate up to the smaller input and print the gcd when a divisor is found.

Learn to reverse a positive integer in C by extracting the last digit, appending it to a reversed accumulator, and printing the result after dividing by ten until zero.
