Programming the Area Calculation in C#

int main() {
   int width, height, area;
   printf('Enter width of the rectangle: ');
   scanf('%d', &width);
   printf('Enter height of the rectangle: ');
   scanf('%d', &height);
   area = width * height;
   printf('Area of the rectangle = %d sq units', area);
   return 0;


Enter width of the rectangle: 5
Enter height of the rectangle: 10
Area of the rectangle = 50 sq units

Explanation of the C# Program to Find Area of Rectangle

  • The program starts with the inclusion of the standard input-output library using ‘#include ‘
  • In the main function, we declare three integer variables: width, height, and area.
  • We then ask the user to enter the width and height of the rectangle. The entered values are stored in the respective variables.
  • The area of the rectangle is then calculated by multiplying the width and height. The result is stored in the ‘area’ variable.
  • Finally, the result of the area of the rectangle is ready on the screen.
