string 的 find（）函数

http://www.cnblogs.com/zpcdbky/p/4471454.html 参考PAT1052

int pos1=line1.find("["); int pos2; while(pos1<=line1.size()){ pos2=line1.find("]",pos1); //找pos1之后的"]" shou[size_s]=line1.substr(pos1+1,pos2-pos1-1); //cout<<size_s<<" "<<shou[size_s]<<endl; size_s++; pos1=line1.find("[",pos2); }

map用法详解

先收录几个自己用惯了的。（应用参考 PAT 1039）

map 的插入。

map <char,node> zhuzi; struct node temp; zhuzi.insert(pair<char,node>(b[i],temp)); map的查找。

zhuzi.count(b[i])；//存在返回1，不存在返回0 map的遍历 map<char,node>::iterator iter; for(iter=zhuzi.begin();iter!=zhuzi.end();iter++){ cout<<iter->first<<" "<<iter->second.now<<endl; }

string 的 substr（）函数

// string::substr #include <iostream> #include <string> int main () { std::string str="We think in generalities, but we live in details."; // (quoting Alfred N. Whitehead) std::string str2 = str.substr (3,5); // "think" std::size_t pos = str.find("live"); // position of "live" in str std::string str3 = str.substr (pos); // get from "live" to the end std::cout << str2 << ' ' << str3 << '\n'; return 0; }
