Variables and primitive types

Variables in QED are almost similar to their C/Java counterparts. A variable definition begins with a type, followed by a name and ending with an optional initialization expression. The primitive types are less numerous though: bool, String, int and float (the latter two using 64 bits). When not initialized, their default value is false, "", 0 and 0.0 respectively.

There is another keyword to introduce: var. A variable declared as var will infer its type based on its initialization value type. Its type cannot change afterwards.

However a var variable with no initialization value can hold any value from any type (a bit like a void* in C).
