C++ How To Calculate the Sum of Array Elements

Share

Calculate the Sum of Array Elements

Loop through the array, and add each element to a sum:

Example

int numbers[] = {10, 20, 30, 40, 50};
int sum = 0;

for (int num : numbers) {
  sum += num;
}

cout << "Sum: " << sum;

Try it Yourself »

Explanation:
sum starts at 0. The loop adds each number to it.
10 + 20 + 30 + 40 + 50 is 150.
