Introduction :
sum of elements in an array c++
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write Sum of Elements in an array in C++ Programming
#include <iostream>
#define MAX_SIZE 100 //Maximum size of the array
using namespace std;
int main()
{
int arr[MAX_SIZE];
int i, num, sum=0;
//Reads size and elements in array
cout<<"Enter size of the array: ";
cin>>num;
cout<<"Enter "<<num<< "elements in the array: "<<endl;
for(i=0; i<num; i++)
{
cin>>arr[i];
}
//Adding all elements
for(i=0; i<num; i++)
{
sum = sum + arr[i]; // Calculating sum
}
cout<<"Sum of all elements of array: "<< sum;
return 0;
}Result
