Here is the Driver Class:

#include #include "Mathstack.h" using namespace std; int main() { // Constants for stack sizes const int STACK_SIZE = 5; const int ADD_SIZE = 4; const int MULT_SIZE = 6; // Create three stacks MathStack stack(STACK_SIZE); MathStack addAllStack(ADD_SIZE); MathStack multAllStack(MULT_SIZE); // Variable to catch values as they are // popped from the stack int catchVar; // Test Add() cout << "Pushing 3 "; stack.push(3); cout << "Pushing 6 "; stack.push(6); stack.add(); cout << "The sum is "; stack.pop(catchVar); cout << catchVar << endl << endl; // Test Sub() cout << "Pushing 7 "; stack.push(7); cout << "Pushing 10 "; stack.push(10); stack.sub(); cout << "The difference is "; stack.pop(catchVar); cout << catchVar << endl << endl; return 0; }

DIRECTIONS:

1) Modify the MathStack class to add the additional functions (mult, div, addAll, multAll) and submit the file here named, MathStack.cpp

2) Modify the Driver class to add the additional functions (mult, div, addAll, multAll) and submit the file here named, Driver.cpp
