How do you multiply two numbers without using multiplication?

How do you multiply two numbers without using multiplication?

1. { public static int multiply(int a, int b)
2. // if both numbers are negative, make both numbers. // positive since the result will be positive anyway.
3. } // if only `a` is negative, make it positive.
4. a = -a;
5. if (b < 0)
6. // initialize result by 0.
7. // if `b` is odd, add `b` to the result.
8. b = b >> 1; // divide `b` by 2.

How do you perform multiplication without using *?

2. int prod = 0,i; printf(“Enter two numbers \n”);
3. scanf(“%d %d”,&firstnum,&secondnum); for(i = 1; i <= secondnum; i++){
4. /* Add the value of firstnum in prod. */ prod += firstnum; }
5. printf(“Multiplication of two numbers is %d”,prod); return 0; }

How do you multiply two numbers without using operator?

3. printf(“Error!! Divisible by 0”); exit(1);
4. if (x * y < 0) { sign = -1;
5. x = abs(x), y = abs(y); // initialize quotient by 0.
6. // loop till dividend `x` becomes less than divisor `y` while (x >= y)
7. } printf(“The remainder is %d\n”, x);
