Basics of C Program

Discover the basic history of the C programming language, its origins with Unix, and its 1988 ANSI formalization, plus its easy, structured style and cross-platform compilation.

Explore how variables act as memory containers for integers, floating-point numbers, and characters in C, and learn to print results with printf using format specifiers.

Learn the rules for C variable declarations: identifiers may include letters and underscores only, cannot start with a digit or double underscores, cannot be keywords, any length, and no spaces.

Learn to read multiple numbers from user input in c using a scanner, ampersand, %d, and a single statement, while avoiding garbage values and using a newline.

Explore the return type in C programs, practice returning integer values such as zero or one, and understand how void differs by returning nothing.

Learn the five categories of operators in C programming: arithmetic, relational, logical, assignment, and bitwise. Practice with ++, --, ==, !=, >, <, &&, ||, and bitwise shifts.

Explore the basics of arithmetic operators in C, including addition, subtraction, multiplication, division, and modulus. The lecture demonstrates integer division behavior, code examples, and how comments improve readability.

Explore short-hand operators in C, including addition, subtraction, multiplication, and division, and observe results via printf with %d while discussing increment behavior.

Explore post increment and pre increment operators in C, discovering how post increment fetches the value before increment and how pre increment increments first, affecting the printed results.

Explore relational operators in C, evaluating expressions with <, >, <=, >=, ==, and !=, and understand how true and false map to 1 and 0 in programming.

Learn how to use logical operators in C programming, including and (&&) and or (||), explore their truth tables, and implement examples with combined conditions and comments.

Learn how bitwise operators in C work, including and, xor, complement, and left and right shift, with binary examples that show how these operations produce results.

Explore the branching statements in C programming, focusing on if, else if, and switch, and examine nested and multiple if structures as key decision making forms.

Learn how the C preprocessor uses macros defined with #define outside main to replace constants, avoiding repeated numbers and simplifying code.

Explore the if statement as a decision making construct, illustrated with flowcharts and code blocks that show conditions, true or false branches, and printing inside the block.

Explore how to implement multiple if statements in a C program, using two blocks for conditions, and see how true or false comparisons like less than hundred control execution.

Learn how nested if statements in C evaluate conditions within conditions and print messages like less than 100, less than 50, and less than 10.

Explore how the if and else control flow and syntax in C, using a voting eligibility example to print eligible or not eligible.

Analyze how to compare three variables A, B, and C in C using if, else if, and logical operators to determine which value is greatest, and print result with printf.

Learn the switch statement in C, understand its basic syntax, use cases and breaks, and implement a switch to drive printf outputs for 0, 1, 2, and 3.

Explore the basics of C programming by learning the ternary operator and its syntax: condition ? expression one : expression two, comparing it with traditional if statements.

Demonstrates swapping two numbers in C using a temporary variable. Shows how to prevent value loss and prints the before-and-after results.

Explore the three main loop types in C program, including the for loop, and examine nested loops with basic syntax and practical examples.

Learn how to use the while loop in C by initializing a counter, checking the condition, and updating the counter to print hi a number of times, avoiding infinite loops.

Compare the do while loop to the while loop, noting the condition is checked at the end and the loop ends with a semicolon, ensuring it executes at least once.

Learn to write a for loop in C, with initialization, condition, and increment, then follow an example that iterates i from 1 to 5 and outputs five results.

Study extended for loop usage to print numbers and stars, explore patterns, and implement nested for loops to produce patterned outputs with line breaks.

Learn to print a four-by-four star pattern in C using i and j indices with conditional checks and spaces. Explore how loops guide star and space placement.

Explore C data types such as int, float, double, long, and char, including declarations, printing with format specifiers, memory sizes, and ASCII character values.

Explore the ASCII character set in C by printing characters and their numeric codes from 0 to 127, and observe extended symbols as values exceed 127.

Master 1d arrays in C by learning how to declare and initialize an integer array, access elements via zero-based indexing, and print all values with a for loop.

Explore two-dimensional arrays in C, declare and initialize a matrix with three rows and four columns, access elements by row and column indices, and print via nested for loops.

Explore user defined functions in C by differentiating them from built-in functions like printf, and learn the three parts: declaration, definition, and calling, plus basic usage.

Learn how to define and use a user defined function in C to add two integers, return the sum, and print the result from main.

Explore recursion by implementing a factorial program in C, where a function calls itself to compute the product and is invoked from main, returning the result for printing.

Explore recursion by using a function that calls itself with n minus one until n equals one, returning the result as shown for 5 factorial and 4 factorial.
