Variables and Their Types in C Programming
In C programming, variables are fundamental components that store data values. They allow programmers to manipulate and manage data efficiently.
What is a Variable?
A variable is a named storage location in memory that holds a value which can change during the execution of a program. Variables are crucial for holding data that your program needs to handle
Declaring and Initializing Variables
To use a variable in C, you first need to declare it by specifying its type and name. Initialization involves giving the variable an initial value.
Example:
int age; // Declaration
age = 25; // Initializationint score = 100; // Declaration and InitializationTypes of Variables in C
Variables in C can be categorized based on their data type and scope.
Data Types of Variables
- int: Used to store integers.
int count = 10;
- float: Used to store single-precision floating-point numbers.
float temperature = 23.5;
- double: Used to store double-precision floating-point numbers.
double price = 99.99;
- char: Used to store a single character.
char grade = 'A';
