    infinite compile time

    hi, i was making a quine using two @@ symbols to represent the string and then testing for them when i cout the string.

    my problem came when i heard that then the text must compile and run, i tried doing this with
    Code:
    system("path, filename");
    but when i would compile it it just ran forever and nothing came up

    i think that the problem is that when i did the system command on the exe the compiler then will compile that, see it again, and repeat,

    i was just wondering if this is my problem or if it is something else

    i use codeblocks and was running it in debug, maybe release would work.

    When you say "compile", do you mean "run"? If your compiler runs without stopping, then chances are that you need a new compiler.

    Or and older one... The only compiler I know of that hangs during compilation, is VS2010's, but only under 32-bit XP.

    A quine isn't supposed to self-compile. It just produces a copy of its source code when executed.

    i use code blocks and i hit f9 which is "build and run", so yes.

    this depends on your definition, some say that it has to output its source, then the source had to run, then that will make it run again.......
    but others just settle for outputting the source

    By that definition, the source will be compiled and run indefinitely (effectively an infinite recursion).

    However, iMalc is correct. The formal computing definition of a quine is a program that outputs its own source.

    What you are alluding to - although you have misinterpreted - is that, in some interpreted languages, a quine can be achieved using a function that, for some specified arguments, returns itself applied to those arguments. That is not possible in C or C++.
    Right 98% of the time, and don't care about the other 3%.

    ok, i see.

    but why would this still not run?
    it just sits there and processes until codeblocks stops working.
