Variable

•Variables include configuration variables that constitute objects, parameters input to functions, and local variables used within functions.

•Enter the variable's data type on the left and its name on the right.

•Except for parameters, you can make a variable a static variable by pressing Alt U. A static variable is a variable that exists only once even if multiple objects are created, and can be accessed regardless of the object that created it.

•The initialization order of static variables proceeds from the object on the left using prefix search.

•You can specify a constant that cannot be changed after initialization by pressing Alt C.
