How would I go about modifying this code to accept characters instead of integers?

```
#include <iostream>
#include <cstdlib>
using namespace std;
struct node {
int key;
node *next;};
int main(int argc, char* argv[]){
if(argc >2) {
int i, N = atoi(argv[1]), M = atoi(argv[2]);
node *t, *x;
t = new node;
t->key = 1;
x = t;
for(i = 2; i<=N; i++){
t->next = new node;
t = t->next;
t->key = i;
}
t->next = x;
while(t != t->next){
for(i = 1; i<M; i++)
t = t->next;
cout << t->next->key<<" has dropped out "<< endl;
x = t->next;
t->next = x->next;
delete x;
}
cout << "winner is " << t->key << endl;
}
return 0;
}
```
