Variables in C programming language: In C programming, variables are used to store and manipulate data. A variable is a named memory location that holds a value. Each variable must be declared with a specific data type, which determines the kind of data the variable can store. Here are some key points about variables in C: 1. Variable Declaration: - Before using a variable, it must be declared. The declaration specifies the variable's name and data type. For example: c int age; // Declaration of an integer variable named 'age' 2. Data Types: - C has several basic data types, including: - int: Integer data type for whole numbers. - float: Floating-point data type for real numbers. - double : Double-precision floating-point data type. - char: Character data type for single characters. - _Bool: Boolean data type fo...
