C++ Program to find the sum of array elements using pointers

---

In this program, You will learn how to find the sum of array elements using pointers in C++.

---

for (i = 0; i < 10; i++) {
   sum = sum + *(ptr + i); 
}

Example: How to find the sum of array elements using pointers in C++.

#include<iostream>
using namespace std;

int main() {

    int arr[5], i, sum = 0;
    int *ptr;

    cout << "Enter 5 numbers:";
    for (i = 0; i < 5; i++) {
        cin >> arr[i];
    }

    ptr = arr;
    for (i = 0; i < 5; i++) {
        sum = sum + *(ptr + i);
    }
    cout << "Sum of array elements:" << sum;

    return 0;
}

Output:

Enter 5 numbers:10 20 30 40 50
Sum of array elements:150
