What is the priority with nested case, for and if loop?

Question

I have a program similar to this:

switch(x)
{ case 1:

for(i=0; i<10; i++)
{
   if ((i==3) || (i==4) || (i==5) || (i==6) || (i==7))
   {
      if (foobar[i])
         break;    // i am talking about this break
   }
}
...further program
break;   /not this break

if foobar[i] is true, would the program break out of the case label or the for loop?

Answer 1

The break follows a LIFO type nature, that is, the last break will come out of the first control structure. So, the break that you chose would break out of the for-loop, not the case.

Answer 2

The for loop.

Please see: break Statement (C++):

The break statement ends execution of the nearest enclosing loop or conditional statement in which it appears. Control passes to the statement that follows the ended statement, if any.
