 1 #include<bits/stdc++.h>
 2 #define LL long long
 3 using namespace std;
 4 int main()
 5 {
 6    char c[100];
 7    while(gets(c))//读取一行
 8    {
 9        stringstream ss(c);//复制
10        string s;bool r=true;
11        while(ss>>s)//从ss读入s中
12        {
13            s[0]=toupper(s[0]);//将小写变为大写
14            if(r==true) {r=0;cout<<s;}
15            else cout<<" "<<s;
16        }
17        cout<<endl;
18    }
