Question

Create a function that takes two numbers as arguments (num, length) and returns an array of multiples of num up to length.

Examples:

arrayOfMultiples(7, 5) ➞ [7, 14, 21, 28, 35]

arrayOfMultiples(12, 10) ➞ [12, 24, 36, 48, 60, 72, 84, 96, 108, 120]

arrayOfMultiples(17, 6) ➞ [17, 34, 51, 68, 85, 102]

Notes Notice that num is also included in the returned array.

Write in C++ language ..

Answer 1

#include <iostream>

using namespace std;

int *arrayOfMultiples(int num, int length);

int main() {
    int *arr = arrayOfMultiples(12, 10);
    for (int i = 0; i < 10; ++i) {
        cout << arr[i] << " ";
    }
    cout << endl;
    delete[] arr;
    return 0;
}

int *arrayOfMultiples(int num, int length) {
    int *arr = new int[length];
    for (int i = 0; i < length; ++i) {
        arr[i] = num*(i+1);
    }
    return arr;
}
