Can someone remake this code to make program work not with char datatype,but int?

CharStack.h

typedef char elem[5];

class CharStack {
    private:
        elem *arr;
        int length;
        int topElem;
    public:   
        CharStack(int);
        ~CharStack();
        char *pop();
        char *top();
        void push(elem);
        int count();
        bool isEmpty();
        bool isFull();
};

CharStack.cpp

#include <iostream>
#include <cstdlib>
#include "CharStack.h"
using namespace std;

CharStack::CharStack(int len) {
    arr = new elem[len];
    length = len;
    topElem = 0;
}

CharStack::~CharStack() {
    delete[] arr;
    cout << "stack deleted. " << count() << " elements in stack upon deletion."
         << endl;
}

void CharStack::push(elem pushableElem) {
    if (isFull()) {
        cout << "\npush() failed; stack is full!\n" << endl;
    } else {
        cout << "\nPushing " << endl;
        for (int i = 0; i < 5; i++) {
            arr[topElem][i] = pushableElem[i];
            cout << pushableElem[i];
        }
        cout << " into stack.\n" << endl;
        arr[topElem][5] = 0;
        topElem++;
    }
}

char *CharStack::pop() {
    if (isEmpty()) {
        return "\npop() failed; stack is empty!\n";
    } else {
        topElem--;
        char *tmpElem = new char[5];
        for (int i = 0; i < 5; i++)
            tmpElem[i] = arr[topElem][i];
        for (int i = 0; i < 5; i++)
            arr[topElem][i] = 0;
        return tmpElem;
        delete[] tmpElem;
    }
}

int CharStack::count() {
    return topElem;
}

char *CharStack::top() {
    if (isEmpty()) {
        return "\ntop() failed; stack is empty!\n";
    } else {
        char *tmpElem = new char[5];
        for (int i = 0; i < 5; i++)
            tmpElem[i] = arr[topElem-1][i];
        return tmpElem;
        delete[] tmpElem;
    }
}

bool CharStack::isEmpty() {
    return (topElem==0);
}

bool CharStack::isFull() {
    return (topElem==length);
}

Are you asking us to rewrite the code for you, or are you asking how you would go about rewriting this code?

[murmuls404]

I just want to know which plces have to be changed to make it work with int

[Duthomhas]

Find the spots that say "Char" or "char" and replace them with "Int" or "int". Your files should also be renamed "IntStack.h" and "IntStack.cpp".

It is worth your time to do this. Your professor is about to teach you something important.

Good luck!

[mcleano]

Ooo now i'm interested, Duoas explain :)

[PanGalactic]

You don't want Duoas to steal the teacher's thunder, now do you?

[mcleano]

I'm more than happy to receive a PM lol.

[Duthomhas]

Done.

I could very well be wrong.

:-)
