harmonic , geometric, arithmetic program

[cNoob]

How do I write a program using the harm,geo,arith formula but requires user input?? I know I cin>> but its suppose to accept user input including all numbers up to 900. How would I write that formula?? ( count / ((1/1)+(1/2)+(1/3)............. ........) I would have to keep going forever?? I am using a while loop ... Please help?? anyone :) Thank you

What exactly do you want the program to do?

#include<iostre am>
using namespace std;
int main()
{

double result=0,top,be low,i;
cout<<"enter 2 numbers:";
cin>>top>>below ;
for(i=1;i<=belo w;i++)
{
result+=(top/i);
}
cout<<"result=" <<result;
return 0;
}


I wrote a program like this I don't know if this is your wish but you should explain what you want exactly

If you're just supposed to accept all numbers up to and including 900, but through user input, it sounds like you want

// while statement that keep input between 1 and 900
while ((inputNum > 900) || (inputNum < 1)) {    
 cin >> inputNum;
}
