需要用到string来储存每一行

#include <iostream>
#include <string>
using namespace std;

int main(){
int n;
int a = 0,b = 0,c = 0;
cin >> n;
for(int i = 0;i < n+1;i++){
string s;
getline(cin,s);
for(int j = 0;j < s.length();j++){
if(s[j] == 'A'){
a++;
}
if(s[j] == 'B'){
b++;
}
if(s[j] == 'C'){
c++;
}
}
}
int res = max(a,max(b,c));
if(res == a){
cout << "human";
}
if(res == b){
cout << "puppy";
}
if(res == c){
cout << "saiyan";
}
return 0;
}
