Question

How would you approach this exercise, as a beginning programmer? It is a classroom exercise, but I am truly trying to understand the best approach.

How far do you have to go in adding up a sequence of numbers for the sum to exceed 10000?
Print the last number added, and the final sum.

This is what I know to write for a simple adding code. Building off of this, how would you answer the above problem?

#include<iostream>
using namespace std; 
int main () 
{
int sum=0; 
int n;
for (n=1; n <250; n=n+1)
sum=sum+n;
cout<<"the sum of 1 through 250 is "<<sum<<endl;
return 0;
}

Answer 1

If you just need to find the limiting values then perhaps this will help:

#include<iostream>
using namespace std; 
int main () 
{
int sum=0; 
int n=1;
while(sum<=10000){
sum=sum+n;
n++;
}
cout<<”to get 10000 you have to add till “<<n<<endl;
return 0;
}
