Thread: 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

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.

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.
