question 48

Multiple Choice

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 ) ;
Stackconst Stack& a_stack) ;
~Stack ) ;
Void pushchar the_symbol) ;
Char pop ) ;
Bool empty ) const;
Private:
StackFramePtr top;
};

• A) void Stack::pushchar the_symbol)
• {
• StackFrame temp_ptr;
• Temp_ptr = new StackFrame;
• Temp_ptr->data = the_symbol;
• Temp_ptr->link = top;
• Top = temp_ptr;
• }
• B) void Stack::pushchar the_symbol)
• {
• StackFramePtr temp_ptr;
• Temp_ptr->data = the_symbol;
• Temp_ptr->link = top;
• Top = temp_ptr;
• }
• C) void Stack::pushchar the_symbol)
• {
• StackFramePtr temp_ptr;
• Temp_ptr = new StackFrame;
• Temp_ptr->data = the_symbol;
• Temp_ptr->link = top;
• }
• D) void Stack::pushchar the_symbol)
• {
• StackFramePtr temp_ptr;
• Temp_ptr = new StackFrame;
• Temp_ptr->data = the_symbol;
• Temp_ptr->link = top;
• Top = temp_ptr;
• }
