Variables

Like many things in D, variable declarations are a lot like C, C++, and Java:

Declare three separate integer variable called myInt, myint, and MYINT.


void main()
{
    int myInt;
    int myint;
    int MYINT;
}

Note that variable identifiers in D are case-sensitive:

In the above example, "myInt", "myint", and "MYINT" are separate identifiers.

In D, all variables have to be declared before they are used.
