According to textbook, we have four categories (static, stack-dynamic, explicit heap- dynamic, and implicit heap-dynamic) of variables. Here is one example illustrating stack- dynamic variables. Please show an example (code) for each of the remaining categories (static, explicit heap-dynamic, implicit heap dynamic). Note: for each code you must indicate the language you used. void f (int n) { //C++ double temp; //here temp is a stack-dynamic variable. }
