Question

Please help C++ language

Instructions Write a program that prompts the user to enter 50 integers and stores them in an array. The program then determines and outputs which numbers in the array are sum of two other array elements. If an array element is the sum of two other array elements, then for this array element, the program should output all such pairs.

Answer 1

#include<iostream>
using namespace std;
//driver program
int main()
{
    //declare the array
    int a[50];
    int i,j,k;
    //loop to input the 50 numbers
    for(i=0;i<50;i++)
    {
       cout<<endl<<"Enter Number "<<i+1<<" : ";
       cin>>a[i];
   }
   //display the 50 integers that are entered
   cout<<endl<<"Elements are ";
   for(i=0;i<50;i++)
   cout<<" "<<a[i];
   //loop to find the sum
   //this loop will choose the number for which we want to find the sum of combinations
   for(i=0;i<50;i++)
   {
       //loop to find the addition. It will choose the first number
       for(j=0;j<50;j++)
       {
           if(j!=i) //skip the number for which we want to find the sum
           { //loop to choose the second number of addition
              for(k=j+1;k<50;k++)
       if(k!=i && j!=k) //skip the first number and the number for which we want to find the sum
       {
           if(a[i]==a[j]+a[k]) //osompare the number with the addition of first and second number
           //display the sum combination
       cout<<endl<<a[i]<<" = "<<a[j] <<" + "<<a[k];
                   }
           }
       }
   }
}

OUTPUT

NOTE: FOR EASY CONVENIENCE FOR FINDING OUTPUT I HAVE CHANGE THE NUMBERS FROM 50 TO 10 AND TAKE THE SNAPSHOT.
