Dynamic MathStack

The MathStack class shown in this chapter only has two member functions: add and

sub . Write the following additional member functions:

Function Description

mult - Pops the top two values off the stack, multiplies them, and pushes

their product onto the stack.

div - Pops the top two values off the stack, divides the second value by

the first, and pushes the quotient onto the stack.

addAll - Pops all values off the stack, adds them, and pushes their sum

onto the stack.

multAll -Pops all values off the stack, multiplies them, and pushes their

product onto the stack.

Demonstrate the class with a driver program.

Using these header files

IntStack.h

// Specification file for the IntStack class #ifndef INTSTACK_H #define INTSTACK_H

class IntStack { protected: int *stackArray; int stackSize; int top;

public: IntStack(int); ~IntStack(); void push(int); void pop(int &); bool isFull(); bool isEmpty(); }; #endif

and

MathStack.h

// Specification file for the MathStack class #ifndef MATHSTACK_H #define MATHSTACK_H

#include "IntStack.h"

class MathStack : public IntStack { public: MathStack(int s) : IntStack(s) {} void add(); void sub(); void mult(); void div(); void addAll(); void multAll(); };

#endif
