C++ Program to find Sum of Array
You are Here:
Find Sum of Array
In the following example, we will sum up all the elements (values) in an array (arr).
Example
C++ Compiler
#include <iostream>
using namespace std;
int main()
{
int i, sum = 0;
int arr[5] = {1, 2, 3, 4, 5};
for(i=0; i<5; i++)
sum += arr[i];
cout << "Sum of array: " << sum;
return 0;
}
Output
Sum of array: 15
Find Sum of any Given Elements in an Array
In the following example, we will sum up any given elements in an array.
Example
C++ Compiler
#include <iostream>
using namespace std;
int main()
{
int i, arr[5], sum = 0;
cout << "Enter any 5 (int) numbers:\n";
for(i=0; i<5; i++)
cin >> arr[i];
for(i=0; i<5; i++)
sum += arr[i];
cout << "Sum of array: "<< sum;
return 0;
}
Output
Enter any 5 (int) numbers:
2 5 8 7 9
Sum of array: 31
