Initialization of a variable in C++ Programming language with Examples

Initialization of a variable:

When a variable is declared, it contains garbage until you assign an initial value.

There are three ways to do this in C++:

• int number = 5; OR int number (5);  OR int number {5};
• double doubleNumber = 1.0;

Examples:

1) int firstNumber = 5,  secondNumber=7, newNumber =8; 

2) double firstNumber = 5.334556; 

3) float area = 64.74; 

4) double volume = 134.64534; 

5) double distance = 45E12 

6) char character ='h'; 

7) bool cond = false;
