Character Variable in C++ Programming

In this lesson, we will discover how to declare and use character variables in C++ programming with this practical guide. Get hands-on with examples and take a quiz to reinforce your understanding.

What is Character Variable

In C++ programming, a character variable can hold a single character enclosed within single quotes. To declare a variable of this type, we use the keyword char, which is pronounced as kar. With a char variable, we can store any character, including letters, numbers, and symbols.

Syntax of Declaring Character Variable in C++

char variable_name;

Here char is used for declaring Character data type and variable_name is the name of variable (you can use any name of your choice for example: a, b, c, alpha, etc.) and ; is used for line terminator (end of line).

Now let's see some examples for more understanding.

Example 1

Declare a character variable x.

char x;

Example 2

Declare 3 character variables x, y, and z to assign 3 different characters in it.

char x='A', y='5', z='#';

Example 3

Declare a character variable x and assign the character '$' and change it value to '@' in the next line.

char x = '$';
x = '@';    //now the new value of x is @

Note

A character can be anything, it can be an alphabet or digit or any other symbol, but it must be single in quantity.
