Can someone fix this and add an array(s)? It will not compile?

Question

include<iostream>

class Hanoi {

private: 
int n;// no. of disks

public: 
Hanoi(int); 
solve(char, char, char int); 
};

void Hanoi :: Hanoi(int a) {

cout << "Enter number of disks : " << endl; 
cin >> a; 
n = a; 
}

void Hanoi :: tower(char from, char use, char to) { 
if (n > 0) { 
tower(n-1, from, use, to); 
cout << "Move disk " << n << " from " << from << " to " << to); 
tower(n-1, use, to, from); 
} 
}

int main(void) 
{ Hanoi h = new Hanoi(); 
h.tower('A','B','C'); 
}

Answer 1

you need

using namespace std;

... and to read again the C++ specifications .... and you may get something like this:

#include<iostream>

using namespace std;

class Hanoi {
public: 
  Hanoi(); 
  void solve(int, char, char, char); 
};

Hanoi :: Hanoi() {
}

void Hanoi :: solve(int n, char from, char use, char to) { 
  if (n > 0) { 
    solve(n-1, from, use, to); 
    cout << "Move disk " << n << " from " << from << " to " << to << endl; 
    solve(n-1, use, to, from); 
   } 
}

int main(void) { 
  Hanoi h; 
  int N;
  cout << "Enter number of disks : " << endl; 
  cin >> N; 
  h.solve(N,'A','B','C'); 
}

Answer 2

Constructors dont have a return type. Hanoi is your class and the following a constructor it need not have a void return type

void Hanoi :: Hanoi(int a)

should be

Hanoi :: Hanoi(int a)

Answer 3

No guys it's not that. I'm not good at programming. I had a bad background with it. I am getting tutored on C++ from scratch. The homework s due tomorrow at 8:30 in the morning. It's just a little late and I needed this help. I tried it on my own and ended up with 6 errors.

Answer 4

Why is everyone coming down on me like that? I needed help. I did not know this would be such a big idea. It is not like I can't go back and understand where I want wrong when my professor goes over it in class tomorrow. Everyone relax. I apologize for asking a question on this website, or shall I say requesting an answer. I thought this is what the website was for. Someone referred me to this website.
