Question

C++ Please take into consideration the instructions and that it is unsigned integers.

Implement the faster algorithm for integer multiplication in C++ as a function, called “multiply”, that takes 2 UNSIGNED integers and returns their multiplication as an unsigned integer. and Test your code in main.

•Represent integers as strings.

•Write a utility function that pads integers with zeros, this will be useful

1.If the 2 integers differ in length

2.In calculating ??10ⁿ and (??+??)10^n/2

Answer 1

#include <iostream>
using namespace std;

int TimesTables (int num);

int main(int argc, const char * argv[]) {
    int number;
    cout << "enter a number to multiply by, with a range of 1-12: ";
    cin >> number;
    if (number < 1 && number > 12)
        return EXIT_FAILURE;
    else {
        int tables = TimesTables(number);
        cout << tables;
    }
    return 0;
}
int TimesTables (int num) {

    for ( int i = 0; num <=12; i ++)
        num = num * i;
    return num;
}
