Answer 2

Answer:

Method 1: // declaration and initialization in single line

int age = 20;

Method 2:

int age; // declaration

Age = 20; // initialization

Method 3:

Dynamic initialization:

#include <iostream.h>

void main()

{

int age;

cout<<”Enter age”;

cin>>age;

return;

}

In method one, the declaration and initialization is done in single line. In the second method, the declaration is done first and then the “age” variable gets initialized. In the third method, the value of “age” variable is set at the run time.
