(1) a static local variable defines its lifetime in the function as the entire source, but its scope remains the same as that of the automatic variable, and can only be used within the function defining the variable. After exiting the function, you cannot use it even though it still ...
to a static variable is changed by its storage mode, which changes its lifetime. Changing a global variable to a static variable changes its scope and limits its use. So the role of static this descriptor is different in different places. ...
statichas a very simple logic to it. If a variable isstatic, it means that it is a global variable, but it's scope is limited to where it is defined (i.e. only visible there). For example: Outside a function: global variable but visible only within the file (actually, the compilati...
