Question

Code in C++ please!

Write a function that takes an array of integers as an input parameter (the address of the first value of the array). It returns nothing. It prints out the array as a single line, with commas between each number, and when the array is finished being printed, it prints an endl; so that we flush the buffer and move to a new line. (I’m having you write this function because you’ll be wanting to print out arrays a lot in the following exercises).

#include <iostream>

using namespace std;

void print_array(int *arr, int size) {
    for(int i = 0; i < size; ++i) {
        cout << arr[i];
        if(i != size-1) {
            cout << ", ";
        }
    }
    cout << endl;
}

int main() {
    int arr[] = {4, 3, 5, 6, 2, 1};
    print_array(arr, 6);
    return 0;
}
