4set集合用法及特点：1，set中的元素从小到大排列且和集合一样没有重复元素；2，set<string>::iterator s.begin() s.end()#include<iostream> # include<cstring> #include<cstdio> # include<sstream> # include<string> #include<set> using namespace std; string wen,str; set<string> dict; int main() { while(getline(cin,wen)&&wen!="#") { stringstream ch(wen); //在文本串中找单个单词 while(ch >>str) dict.insert(str); printf("%d\n",dict.size()); dict.clear(); } return 0; }
#include<iostream>
# include<cstdio>
# include<string>
# include<map>
# include<cstring>
# include<sstream>
using namespace std;
map<string ,int> m;
string str,ch;
/* int main()

while(i<len&&'a'<=str[i]&&str[i]<='z')
ch+=str[i++];
