【Kingdao Computer Test】-String-Capitalize the first letter-Peking University

Marked as difficult questions, but it feels like that, remember the function to capitalize. The difficulty of the school's retest questions and the leetcode is too big.

#include <iostream>
#include <string>
using namespace std;
int main(){
    string s;
    getline(cin,s);
    if(s.length()!=0)
        s[0]=toupper(s[0]);
    for(int i=0;i<s.length();i++){
        if(s[i]==' '||s[i]=='\t'||s[i]=='\r'||s[i]=='\n')
            s[i+1]=toupper(s[i+1]);
    }
    cout<<s<<endl;
}
