Write a program to compute and print the area of a square with given height and width. The formula to compute the area of square is

                               Area = height * width ;

Example in C

#include < stdio.h >

#include < conio.h >

void main ( )

{

      int   height , width , area ;

      height = 13 ;

      width = 5 ;

      area = height * width ;

      printf ( " Area of square is : %d " , area ) ;

}

Example in C++

#include < iostream >

using namespace std ;

int main ( )

{

      int   height , width , area ;

      height = 13 ;

      width = 5 ;

      area = height * width ;

      cout << " Area of square is : " << area ;

      return 0 ;
