2. What is C Programming?
• C is a general-purpose, procedural
programming language.
• Developed by Dennis Ritchie in 1972 at Bell
Labs.
• Widely used for system and application
software.

3. Features of C
• • Simple and efficient
• • Mid-level language
• • Structured programming
• • Rich library
• • Portable and extensible

4. Structure of a C Program
• #include <stdio.h>
• int main() {
• printf("Hello, World!n");
• return 0;
• }

5. Basic Syntax
• • Header Files
• • Main Function
• • Statements and Semicolons
• • Braces {}
• • Comments // or /* */

6. Data Types in C
• • int - Integer
• • float - Floating point
• • char - Character
• • double - Double precision floating point

7. Variables and Constants
• • Variable: Stores data during program
execution
• • Constant: Fixed value that does not change
• Example:
• int a = 10;
• const float pi = 3.14;

8. Operators in C
• • Arithmetic: +, -, *, /
• • Relational: ==, !=, >, <
• • Logical: &&, ||, !
• • Assignment: =, +=, -=
• • Increment/Decrement: ++, --

9. Control Statements
• • if, if-else
• • switch
• • for loop
• • while loop
• • do-while loop

10. Functions in C
• • Blocks of reusable code
• • Can take parameters and return values
• Example:
• int add(int a, int b) {
• return a + b;
• }

11. Conclusion
• C is a foundational language in programming.
• Understanding C helps in learning other
languages and system-level programming.
• It remains relevant in many software and
embedded systems.
