Understanding Data Types in C

In this guide, we’ll explore the different data types in C. Data types are essential because they tell the compiler what kind of data a variable can hold.

Types of 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.
