    Reinitializing a variable

    I am very new to the C programming language and I am working on a project that involves reinitializing a varialbe(s).

    Could someone clue me in how to do this, I am confused

    You can say, for example:

    i=0;

    anywhere in the program - you just have to declare them at the beginning; the values can (usually) be changed anywhere.

    If you initialize like so:

    int i = 5;

    Then, anywhere that the integer i is in scope, you can change its value:

    i = 2;
    i=0;

    But if you declare the integer as constant:

    const int i = 5;

    The compiler won't let you put another value into this variable.

    i = 8 // compiler will bomb here.
