26. Program that sums the sequence of integers assuming that first integer read specifies the number of values remaining to be entered.

Chapter 6: 

Looping Structures

Programming Exercise

Problem # 26:

Write a program that sums the sequence of integers assuming that first integer read specifies the number of values remaining to be entered. The program should read one value per input statement. A typical input sequence might be 5 100 200 150 300 500. The first integer 5 indicates that subsequent five values are to be summed.

Solution:

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    int n1, n2, n3, sum=0;
    cout<<"\nEnter a number:";
    cin>>n1;
    for(n2=1;n2<=n1;n2++)
    {
        cout<<"Enter a number:";
        cin>>n3;
        sum=sum+n3;   
    }
    cout<<"\nThe sum of the subsequent values after first integer are:"<<sum<<endl;
    getch();
}
