arguments

void show()

{

num x=num(4,5,7); // Explicit call

num y(1,2,8); // Implicit call

x.show();

}

OUTPUT

a= 4 b= 5 c= 7

a= 1 b= 2 c= 8

Explanation: In the above program, x and y are objects of class num. When objects are created,

three values are passed to the constructor. These values are assigned to the member variables.
