In C++, write a method that compute squares using pointers

Question

Create a method that takes in a reference int and an int array. Return the memory address of the first element of the array.

Explanation

Within the computerSquares function, create a for loop that loops from 0 to the length of the array, n. Within the for loop, assign the value ((k+1)²) into the current element the for loop is iterating at. Once the for loop has finished iterating, then return the memory address of the first element of the array &arr[0].

Once the computerSquares function is done, the program will return the main method where the program will print the resulting values of the computerSquares function, using ptr[i].

#include <iostream>
using namespace std;
int* computeSquares(int& n, int arr[])
{
n = 10;
for (int k = 0; k < n; k++){
arr[k] = (k+1) * (k+1);
}
return &arr[0];
}
int main()
{
int m;
int arr[10];
int* ptr = computeSquares(m, arr);
for (int i = 0; i < m; i++)
cout << ptr[i] << ' ';
}
