Consider the following C program
int main() 
   int x, y, m, n; 
   scanf ("%d %d", &x, &y); 
   /* x > 0 and y > 0 */
   m = x; n = y; 
   while (m != n) 
   { 
      if(m>n) 
         m = m - n; 
      else
         n = n - m; 
   } 
   printf("%d", n); 
}
What does the program compute?
  • a)
    x + y using repeated subtraction
  • b)
    x mod y using repeated subtraction
  • c)
    the greatest common divisor of x and y
  • d)
    the least common multiple of x and y
Correct answer is option 'C'. Can you explain this answer?

Consider the following C programint main(){int x, y, m, n;scanf ("...
"%d%d%d%d", &x, &y, &m, &n);printf("%d\n", (x + y) * (m - n));return 0;}In this program, the user is prompted to enter four integers: x, y, m, and n. These values are then stored in the corresponding variables using the scanf function. The program then calculates the result of the expression (x + y) * (m - n) and prints it using the printf function. Finally, the program returns 0 to indicate successful execution.
