Understanding Variables in C++

In this tutorial, we’ll explore variables in C++, which are essential for storing and managing data. You’ll learn how to declare and use variables effectively in C++.

What Are Variables?

Variables in C++ store data that we can use in our programs. Here’s how to declare a variable:

// Declaring variables in C++
int age = 25;      // integer variable
double salary = 50000.50; // double variable
char grade = 'A';   // character variable

Each data type serves a specific purpose, like holding numbers or characters.
