/prog/ - Programming help

Hi,

This is my first time posting to a 4Chan text board so i apologize if i seem a bit selfish asking for help in my first post but this is the only board that im confident has frequent users.

Here is my question:
For a homework assignment in C/C++ i need to have some code that will terminate the program if the user inputs a value outside of a preset range. Ive looked through the book and all the class notes i have and cant seem to find any reference on how to make that happen. I know someone here should be able to give me an idea on how to do this.

Lol, here's a student repeating what his programming 1 teacher told him believing it's the absolute truth in the Universe.

A good programmer will use the right tool for the right job, and break (and continue) is the right tool so many times for a number of reasons like avoiding duplicate code (duplicate code is a bad thing), simplifying loops, or not making your function wider than taller because of fugly indentation, plus a few purist causes in where you'd like to break rather than to indent differently code that works at the same level or in a similar set of cases. Even goto has its uses in languages when you can't break twice or low-level language when you need to achieve some extremely cunning hack there's no good way without.

there's no reason to use goto or break in a high-level language like c.
stop using your shitty formatting as an excuse for writing lousy code.

Lol, first you're University Hello World-purist enough to say you shouldn't use break, then you call code indentation "shitty formatting". Ok; in a few (5-6) years you'll get to work on real code and we'll see.

P.S.: How's your homework?

void input_loop() {

 char i = get_input();

 if (inrange(i)) {

  do_stuff();

  input_loop();

 }

}

Recursion is superior! Iteration considered harmful!

(define (input-loop)

  (when (inrange (get-input))

    (do-stuff)

    (input-loop)))

Terminal recursion for teh win!

recursion is just goto. therefore it fails.

Hey people, don't run the polite n00b out of town on a fucking rail now. We could be witnessing the birth of a new C programmer here, and that's something you don't get too often anymore.

because it's not true.
if you want to get a reaction, you have to say something true.
like this:

ruby is slow.
python is ugly.
no one uses smalltalk for anything other than trying to prove that it's better than ruby.
java, smalltalk, and python are the only languages worse than ruby.
