Given the following stack declaration, which of the following function definitions would correctly push an item onto the stack?

struct StackFrame { char data; StackFrame *link; }; typedef StackFrame* StackFramePtr; class Stack { public: Stack( ); Stack(const Stack& a_stack); ~Stack( ); void push(char the_symbol); char pop( ); bool empty( ) const; private: StackFramePtr top; }; a. void Stack::push(char the_symbol) { StackFrame temp_ptr; temp_ptr = new StackFrame; temp_ptr->data = the_symbol; temp_ptr->link = top; top = temp_ptr; } b. void Stack::push(char the_symbol) { StackFramePtr temp_ptr; temp_ptr->data = the_symbol; temp_ptr->link = top; top = temp_ptr; } c. void Stack::push(char the_symbol) { StackFramePtr temp_ptr; temp_ptr = new StackFrame; temp_ptr->data = the_symbol; temp_ptr->link = top; } d. void Stack::push(char the_symbol) { StackFramePtr temp_ptr; temp_ptr = new StackFrame; temp_ptr->data = the_symbol; temp_ptr->link = top; top = temp_ptr; }
