Is it possible to write a function that returns a pointer? What possible problem could the programmer encounter if the address of a function’s local variable (i.e., pointer) was returned to the calling function?
What will be an ideal response?
Sure, it is possible to return a pointer. If a local variable’s address is returned to the calling function, the variable goes out of scope. The pointer will be pointing at a section of memory that is no longer valid. If another function is called, and new variables are placed on the stack, that pointer would then be pointing at that data.
