    Arrow declare consts~

    Howdy everyone.

    an simple question. I declare the const like this:

    const int x;
    x=0;

    but it failed when compiling. Could we declare the const first and valued it later ?

    Constants are declared like this.
    const int x = 0;

    What you did was say, i want this integer x to be constant. Then the compiler says ok, now nothing can change it. Then you said i want to change it now to 0. That is why it didn't let you, you cannot do that with 2 statements like you have. Put them all on the same one and you will be fine.
