Question

I am trying to figure out what is wrong with my C++ code. This code is implementing the stack structure within a class. The output should be: X = 3, Y = 9, 7, 13, 4, 7 in a stacked form. My code outputs x = 3 and y = 9 but does not output 7,13,4,7, and instead outputs random numbers and zeros.

My Output:

Header File:

#include <cassert>

class stackType {
   
    private:
        int arrayStack[];
        int stackTop;
        int stackSize;
    public:
        stackType();
        bool isEmpty();
        bool isFull();
        void push(int newData);
        void pop();
        int top();
        void intStack();
};

stackType::stackType(){
    stackTop = 0;
    stackSize = 100;
}

bool stackType::isEmpty(){
    return (stackTop == 0);
}

bool stackType::isFull(){
    return (stackTop == stackSize);
}

void stackType::push(int newData){
    if (!isFull()){
        arrayStack[stackTop] = newData;
        stackTop++;
    }
    else{
        cout << "Can't push when stack is full !" << endl;
    }
}

void stackType::pop(){
    if (!isEmpty()){
        stackTop--;
    }
    else{
        cout << "Can't pop from an empty list !" << endl;
    }
   
}

int stackType::top(){
    assert (stackTop != 0);
    return arrayStack[stackTop-1];
}

CPP File:

#include <iostream>
using namespace std;

#include "arrayStack.h"

int main()
{
stackType stack;
int x;
int y;

// Show what is output by the following segment of code:
x = 4;
y = 0;
stack.push(7);
stack.push(x);
stack.push(x + 5);
y = stack.top();
stack.pop();
stack.push(x + y);
stack.push(y - 2);
stack.push(3);
x = stack.top();
stack.pop();
cout << "x = " << x << endl;
cout << "y = " << y << endl;
while (!stack.isEmpty())
{
cout << stack.top() << endl;
stack.pop();
}
system("PAUSE");
return 0;
}

Explanation / Answer

Hi There :)

Your entire code is fine except

int arrayStack[];

---> you cant declare the static array without size.

Correction : int arrayStack[100];

just change the above line and program is good to run.
