Question

Write a function that takes a size, creates a new array of that size with all zeros, and returns the array. If the size is not a valid size for an array, do not return a valid array. The function should use the signature: int * newZeroArray(int size) For example: Result Test int size 5; int A = newZeroArray(size);

#include <iostream>
using namespace std;


int * newZeroArray(int size) {
        //your code here
}

int main() {
        int size = 10;
        int * A = newZeroArray(size);

        for(int i = 0; i < size; i++)
                cout << A[i] << " ";
        cout << endl;
}

Given below is the completed code. Please do rate the answer if it helped. Thankyou.
#include <iostream>
using namespace std;

int * newZeroArray(int size) {
if(size <= 0)
return nullptr;
else{
int *arr = new int[size];
for(int i = 0; i < size; i++)
arr[i] = 0;
return arr;
}
}

int main() {
int size = 10;
int * A = newZeroArray(size);

for(int i = 0; i < size; i++)
cout << A[i] << " ";
cout << endl;
}
