How to Loop?

[jamonathin]

How can you run just a basic loop? What I'm trying to do is make this program (http://www.compsci.ca/v2/viewtopic.php?t=8675) and I can do everything, but loop. Any suggestions?

If you're using C, something like

code:

while (1) {   // code goes here }

should work.

If you're trying to make a for loop, then

code:

int i; for (i=0;i<5;i++) {   // code goes here }

should work.

Im using C++, and so how would I go about exiting the loop though. The type of loop Im looking for is just like the one in turing

Turing:

loop exit when . . . end loop

Well, something like:

c++:

int i; while (true) {    std::cin >> i;        if (i == 53)    {       break;    } }

sweet, thanks man.

I came across a C++ book and another way to infinite loop is ->

code:

for (; ;){ //code here }

I think it works

Or, to be cute...

c++:

#define EVER ;; for(EVER) { }

Being cute in such languages isn't cute.

The problem is that some student will come in here, see that, and consider it the best way to loop.

... and his teacher will cut his mark for redundant code, illegal use of vars and not following instructions, and if you have a teacher like ours, dam someone is in deep s**t

s'not a var, just a text substitution

Programming's an art, NOT a science. This is very debatable, but that's my opinion. If you find a creative or fun way of doing something, you shouldn't be penalised for it. As long as it's not really bad coding style....like goto or something. I ALWAYS make my first for loop var 'c' so i can go:

code:

for(int c = 0;c <= 100; c++){cout<<"cat"<<endl;} //notice the //c++......hehe

Which is bad, because it means that the code you're seeing, and the code the compiler is seeing are different.

Never said it wasn't bad, it's just not an illegal use of variables. It's a bad practice, that's all.

And Cinjection - I do that too
