data type intro

1. Basic Data Types in C Understanding fundamental data types

2. Introduction C provides several standard data types to represent numbers, characters, etc. They form the foundation for all programs.

3. Primary Data Types int - Integer numbers (e.g., 5, -20) char - Single character (e.g., 'A', 'z') float - Single precision floating point numbers double - Double precision floating point numbers void - Represents no value

4. Examples of Primary Data Types int age = 25; char grade = 'A'; float pi = 3.14f; double bigPi = 3.1415926535; void functionName(); // returns nothing

5. Type Modifiers short, long, signed, unsigned can modify basic types Examples: short int, long int, unsigned int, long double

6. Summary Basic types are building blocks of C programs. Choosing the right type ensures efficient memory usage and correctness.
