Question

Write an algorithm that calculates A*B without multiplication (A and B are integers) in laguage C

Answer 1

Answer:

4 * 5 = 20

How it works?

4 added 5 times

(4 + 4 + 4 + 4 + 4) = 20

Explanation:

//Multiplication of two numbers

#include <stdio.h>

int main()

{

  int x, y; //declaring two integer variable

  int product = 0; //initializing product to zero

  printf("Enter two integers:\n");

  scanf("%d%d", &x, &y);

  //loop to calculate product

  while(y != 0)

  {

     product += x;

     y--;

  }

  printf("\nProuduct = %d\n", product);

  return 0;

}
