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
Actually, effect you're trying to achieve is more correctly by the conditional variable (at least in terms of procedural programming): 
bool exiting=false;
for (i = 0; i < 100 && !exiting; i++)
{
for (j = 0; j < 100 && !exiting; j++)
{
if (i+j == 100)
exiting=true;
}
}


or may be even
for (j = 0; j < 100; j++)
{
if (i+j == 100)
{
exiting=true;
break;
}
}
}
