Question about a factorial program

I was wondering if anyone can help, because i cn get it to work in java but not in C++.

#include <iostream.h>

void main()
{
int input;
cout<<"Type in a number\n";
cin>>input;
for (int i = 1; i <= input; i++)
{
input = i * input;
}
cout<<input
}

like i said, i got it to work injava, but whenever i type something in here i get something totally different (like -1899959296 for 5 when it should be 120).

try it with this line instead:

cout << "Type in a number" << endl;

Heh, I should have guessed. Lots of times whe ni have something like this i can use endl; and fix it. It's like the solution to all the world's problems or something....

No cheating Pete, figure it out for yourself. No using Math.PI. You have to learn the functions

Hmm...it's still not working.

try putting endl after all the lines

It's because of the way you're using the input variable as a control variable for the loop. You can do it the way you're doing it with an extra variable, like this:

Code:

---

#include <iostream.h>

void main()
{
        int input;
        int output = 1;
        cout<<"Type in a number" << endl;
        cin>>input;
        for (int i = 1; i <= input; i++)       
                output *= i;
        cout<< output<< endl;
}

Cool, it works now. Thanks a lot for your help :)
