Expert Solution

Step 1: Understanding the problem

Declaring data type in C++

When the variables in the example above are declared, they have an undetermined or garbage value until they are assigned a value for the first time. But it is possible for a variable to have a specific value from the moment it is declared. This is called the initialization of the variable.
In C++, there are same ways to initialize variables as in C Language.

Syntax:

type identifier = initial_value;

Example:

int a = 10;  //integer variable declaration & initialization.
