I think I have figured out how to do it, it complies with me and I think its right but the output comes out and immediately goes away (Dos screen), can anyone help?

I somehow tried to play with output

(Toggle Plain Text)

cout << i;

but I couldn�t figure it out.

Thanks.

(Toggle Plain Text)

#include <iostream>
#include <stdlib.h>

using namespace std;

int main()
{
 
 float sum =1;
 int i=2;
 while (sum < 5.0)
 {
   sum = sum + 1/(float)(i);
   i++;
 }
 
    cout << i;
    
}

If you're using Windows, you can use the getch() function to return the first character press, essentially waiting for the user to press any key:

cout << "Press any key to continue...";
getch();

return 0;

You should return an integer if you're going to define main as an int - most people return 0. Put that just before the closing brace.

Alternatively, you could also include stdlib.h and use
system("PAUSE");
If you don't plan on porting to other operating systems and such.
