[SOLVED] SOLVED: C++ allows pointers to stack-dynamic variables.

C++ allows pointers to stack-dynamic variables. Consider the following C++ function: int twice(int x) { int *y; *y = x * 2; return *y; } Will the above function compile in C++? Is it correct? If not, under what circumstances will it fail and how should it be corrected? Consider one other language that has pointers. Does that language have the same problem? Explain.
