**Array elements summation** is a famous task for programmers, as We can take the array elements from the user also, Similarly we can **compute sum** of element of array also. Here is an example which is able of compute sum of the elements of an array:

// Array Elements summation in C++ #include <iostream> using namespace std; int main() { const int arraySize = 10; // constant variable indicating size of array int a[ arraySize ] = { 87, 68, 94, 100, 83, 78, 85, 91, 76, 87 }; int total = 0; // sum contents of array a for ( int i = 0; i < arraySize; ++i ) { total += a[ i ]; } cout << "Sum of array elements: " << total << endl; }

In the above example we created and initialized an array and now we are going to compute sum of elements of this array. We defined a variable “total” and then we applied a for loop in order to get access to every element of the array, then we added every element into the “total” and at the end we have the computed sum**. Â **Now after the loop whenÂ we **compute sum** and displayed it on the display.
