box function problem

Firstly, sorry i posted this twice but i had connection problems and thought it hadnt posted the first time.
Here is my code for a box function.

Code:

---

#include <iostream>
using namespace std;

void box(int length, int width, int height);

int main()
{
        box(7, 20, 4);
        box(50, 3, 2);
        box(8, 6, 9);

        return 0;
}

void box(int length, int width, int height)
{
        cout << "The volume of the box is " << length * width * height << "\n";
}

---

and here is the output:

The volume of the box is 560

In the book im using the output is this:

volume of box is 560
volume of box is 300
volume of box is 432

why is my code only outputting the first line?

ive checked the code and i can't spot any mistakes. Im ahaving the same problem with other function codes. Please help. Thanks

The output of this program, as you posted is

Code:

---

The volume of the box is 560
The volume of the box is 300
The volume of the box is 432

If you are not seeing the output, perhaps you need to scroll down.

no, scrolled down all the way and no output, but thanks.

Well, that's all I can do. There's nothing wrong with your program; perhaps there's a compiler issue if you're using some bizarre/antiquated compiler, but g++ and Microsoft's Visual Studio handle it just fine.

i am using microsoft visual so it cant be that. just one of those annoing set backs newbies seem to encounter, never mind.

Because you are using "\n", which you shouldn't be using. Use cout << ... << endl; instead. It acts a newline, and it also flushes the output buffer.

problem solved! it was the way i was debugging the programming. i was using 'right click > run to cursor' but when i realised you just press ctrl and F5 it worked fine. thanks

Wrong. Using "\n" is fine, and overusing endl is an extremely common newbie mistake. The only time you want to explicitly flush cout is when you are writing progress messages during a lengthy operation. It is automatically flushed at program exit and when you request input from cin.
