Basic Data Types in C Language

• There are five basic data types in C: integer, character, floating point, double, and void
• Integer data type: int, represents whole numbers, e.g. 1, 2, 3, etc.
• Character data type: char, represents single characters, e.g. 'a', 'A', etc.
• Floating point data type: float, represents fractional numbers, e.g. 3.14, -0.5, etc.
• Double data type: double, represents larger floating point numbers, e.g. 3.14159, -0.0005, etc.
• Void data type: void, represents no value, used for functions that do not return a value

Pointers in C Language

• A pointer is a variable that stores the memory address of another variable
• Declared using the asterisk symbol (*), e.g. int *ptr;
• Pointers can be used to indirectly access and manipulate the value stored at the memory address they point to

Functions in C Language

• A function is a block of code that can be called multiple times from different parts of a program
• Declared using the function return type, function name, and parameters in parentheses, e.g. int add(int a, int b) { ... }
• Functions can take arguments, return values, and perform specific tasks
