对于c++primer中前面几章的练习以及书上的例子

#include <cstdlib>
#include <iostream>
#include<complex> 
#include<utility> 
using namespace std;

int main(int argc, char *argv[])
{
    complex<double> purei(0,7); 
    cout<<purei<<endl; 
    pair<string,string> author("james","joyce");
    string firstBook;
    if(author.first=="james"&&
       author.second=="joyce")
       firstBook="Stephen Hero";
