Here is my code, what's the problem?

#include <algorithm>
#include <iostream>
#include <vector>
#include <sstream>
#include <string>
#include <cstdlib>
#include <cstdio>
#include <iomanip>

using namespace std;

int main(){

    int count[26];
    int max = 0;
    char answer = '-';
    for (char p = 'a'; p < char('z') + 1; p++)
    {
        count[p] = 0;
    }
    char c;
    while (cin.get(c))
    {
    count[c]++;
    }

    for (char p = 'a'; p < char('z') + 1; p++)
    {
        if (count[p] > max){
            max = count[p];
            answer = p;
        }
    }

    cout << answer;

}
