stack class Implement template stack class that is capable of storing integer and string values. Write both header and implementation in one file (stack.h) Private data fields: data: An array with maximum size of 20. (Declare a constant in stack.h called MAX_SIZE and set it to 20.) size: stores the current number of elements in the stack. Public interface: stack0: constructs an empty stack. push(T val): inserts a new element (val) of type T (T could be integer or string) into the data. If the data array is full, this function should throw an overflow_error exception with error message "Called push on full stack." pop0: removes the last element from data. If the data array is empty, this function should throw an outofrange exception with error message "Called pop on empty stack. top0: returns the top element of stack (last inserted element). If stack is empty, this function should throw an underflow_error exception with error message "Called top on empty stack.. empty0: returns true if the stack is empty otherwise it returns false. main.cpp test harness Use this main.cpp file for testing your stack Use this main.cpp file for testing your stack. #include #include #include #include "stack"h" > test; cout stack1 ; if (stackl.empty)) cout stack2; cout stack3; cout stack4; cout stack5 cout
