In this C++ tutorial, you shall learn how to write a program to find the sum of elements in the given integer array.

## C++ Find Sum of Elements in Integer Array

To find the sum of elements in an integer array, loop through the elements of this array using a For Loop or While Loop, and accumulate the sum in a variable.

## Examples

### 1. Find sum of integers in the array {2, 4, 6, 8}

In the following example, we take an integer array initialized with some elements, and find the sum of the elements of this array using a For Loop.

main.cpp

```#include <iostream>
using namespace std;

int main() {
int x[] = {2, 4, 6, 8}; //integer array
int len = sizeof(x) / sizeof(x); //get array length
int sum = 0; //initialize sum with 0

for (int i = 0; i < len; i++) {
sum += x[i]; //accumulate sum
}

cout << "Sum : " << sum << endl;
}```

Output

```Sum : 20
Program ended with exit code: 0```

## Conclusion

In this C++ Tutorial, we learned how to find the sum of elements of an integer array, with the help of example C++ programs.
