If you find yourself breaking out of two loops you should reduce yoru code
to a couple functions or flags to control the flow.

Sina:
Break is awesome when you have one single loop, but you can't break out of
two loops, can you? It was just the first thing that came to mind because
I've seen it used (and used it) like that.

tyler, this is a horrible example of goto, my friend. 

  

That's what break is for. 

  

Take care,

I really really highly recommend you avoid goto. This isn't basic, and
they're not very useful except for in some odd cases, far and few between.
Such as jumping out of two nested loops like so:
int i, j;
for (i = 0; i < 100; i++)
{
for (j = 0; j < 100; j++)
{
if (i+j == 100)
goto botttom;
}
}
bottom:
//do something here
if you want to compare strings, do something like this:
if (input == "north")
{
GoNorth();
}
else if (input == "south")
...
else ...

Hi. 

I'm writing if tests in c++ with the goto command. 

I want to do text games and I'm using these commands for that. 

But it doesn't work, so I must do something wrong. 

Can you give me an example how this is done with a string please?
