I am trying to get my code to work for chars it works for ints but when I try to use it for chars it gives me the error invalid conversion from `const char*' to `char' here is my code

#include <iostream>
#include <fstream>
#include <map>
#include <string>
#include <iterator>
using namespace std;



class mystack
{
public:
int size;
char* stacker;
int topg;
char a;
char data;
mystack(){
topg = -1;
size = 1;
stacker =new char[size];
}
~mystack(){
if(stacker) delete[] stacker;
}
char push(char a){

size++;
topg++;
stacker[topg] = a;
return 0;
}
char pop()
{
char data = stacker[topg];
topg--;
cout << data << endl;
return data;
}
int top(){ return topg;}

};

int main()
{
mystack a;
a.push("a");
a.push();
a.pop();
cout << a.top() << endl;
system("pause");
}

I just need to understand why exactly i am getting this error and what I can do to change it

Next time highlight the line that the compiler is complaining about (yes, it does give you a line). Otherwise we have to manually dig through it, like I just did.

Your function is declared asbut your calling it asYou need to pass a char, not a string (i.e. char*). "a" is a string but 'a' is a char.

Sorry about that I will definatly rememebr for next time thanks for the quick reply though

ccould you elaborate a little more because I have tried changing my function char push(char a) to just char push() and other things as well with no success I am still kind of lost.

Your function definition is fine, the problem is with how your calling it, as I said above.

Your doingbut you need to do.

Also remove the line after your first push, as it will give an error. That is, remove this

Oh wow see I thought I had tried that but, I guess not because it did work thank you so much for your help I really apperciate it
