Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
#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; }
