Understanding Data Types in C

C supports several fundamental data types:

• int: Used to store integer values (whole numbers).
  • Example: int age = 30;
• float: Used to store single-precision floating-point numbers (decimals).
  • Example: float salary = 2500.50;
• double: Used to store double-precision floating-point numbers for more accuracy.
  • Example: double pi = 3.14159;
• char: Used to store a single character.
  • Example: char initial = 'A';
• void: Indicates that a function does not return a value or that a pointer does not have a specific type.
  • Example: void myFunction() { /* code */ }

Understanding these data types is crucial for defining the type of data your variables can hold, which in turn helps in writing efficient C programs.
