大佬们帮忙看看这个代码哪里错了吧

#include<bits/stdc++.h>
using namespace std;
string s,s1;
signed main(){
	int len=0,ans=0,xb=0;
	bool b=0;
	cin>>s1;
	for(int i=0;i<s1.length();i++){
		if(s1[i]>='A'&&s1[i]<='Z'){
			s1[i]+='a'-'A';
		}
	}
	while(cin>>s){
		for(int i=0;i<s.length();i++){
			if(s[i]>='A'&&s[i]<='Z'){
				s[i]+='a'-'A';
			}
		}
		if(s==s1){
			ans++;
			if(b==0)xb=len,b=1;
		}
		len++;
	}
	if(ans==0)cout<<"-1";
	else cout<<ans<<" "<<xb;
}
