c++简洁代码

mark一下他人写法

#include<bits/stdc++.h>
using namespace std;

int main() {
    string s;
    while(cin >> s);
    cout << s.size();
    return 0;
}

自己写法

#include<iostream>
using namespace std;
int main(){
    string sentence;
    while(getline(cin, sentence)){
        while(sentence != ""){
            int position = sentence.find(' ');
            if(position != sentence.npos){
                sentence.erase(0, position+1);
            }else{
                cout << sentence.length() << endl;
                break;
            }
        }
    }
}
