Contrary to popular stupidity, there is nothing wrong with using goto or continue. both perform the same thing in assembler, a jump to an address.
Normally, you don't need to use them. However, you cannot ever rule their use out 100%-- if you try, I'm sure you can find an example of logic that would require the use of each one, with no other way to do it.
But it is incorrect to simply rule both statements out simply because you "feel" or some other fool told you that you shouldn't ever use them.
Every tool in your toolbox has a purpose. Learn to use them all well, at the appropriate time. Only an amateur beats on a nail with pliers when the hammer is right there in the toolbox...
Developing is all about being open-minded to conventional and non-conventional solutions. 'goto' and 'continue' are valid, C statements supported by all C/C++ compilers.
