* C Program to find Product of 2 Numbers using Recursion
int product(int, int);
int a, b, result;
printf("Enter two numbers to find their product: ");
scanf("%d%d", &a, &b);
result = product(a, b);
printf("Product of %d and %d is %d\n", a, b, result);
int product(int a, int b)
if (a < b)
return product(b, a);
else if (b != 0)
return (a + product(a, b - 1));
$ cc pgm20.c $ a.out Enter two numbers to find their product: 176 340 Product of 176 and 340 is 59840
