i want make this code to take the number from user in c++

Question

this is an insertion sort code , i want to edit this code so users can input random numbers and sort them.
this is the code:
....
// sort.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
using namespace std;

void swap(int *a, int *b) {
int temp = *a;
*a = *b;
*b = temp;
}

void insertionSort(int arr[], int n) {
int i, j;
for (i = 1; i < n; i++) {
j = i;
while (j > 0 && arr[j - 1] > arr[j]) {
swap(&arr[j], &arr[j - 1]);
j--;
}
}
}

void printArray(int arr[], int size) {
for (int i = 0; i < size; i++)
cout << arr[i] << " ";
}

int main() {
int arr[] = { 5, 2, 10, 6, 1, 3,8 };
int n = sizeof(arr) / sizeof(arr[0]);
insertionSort(arr, n);
printArray(arr, n);

return 0;
}

Answer 1

Use cin >> varName; to get input
Then just use varName (the name of your variable) to access the input
