Question

How to write a recursive function in C++ that gives the sum of up to 10 integers from an array. If there are more than 10 integers entered by user, it takes only the first 10. If less than 10, it continues with the calculation.

Answer 1

#include <iostream>
using namespace std;

int getSum(int arr[], int size, int index){
    if(index<size && index<10){
        return arr[index]+getSum(arr,size,index+1);
    }
    else{
        return 0;
    }
}

int main() {
    int arr[] = {1,2,3,4,5,6,7,8,9,10,11,12};
    cout<<getSum(arr,5,0)<<endl;
    cout<<getSum(arr,12,0)<<endl;
    return 0;
}
