本文主要是介绍c++ unique container set,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
#include <iostream>
#include <uuid/uuid.h>
#include <ctime>
#include <string>
#include <sstream>
#include <unistd.h>
#include <fstream>
#include <pthread.h>
#include <queue>
#include <set>
#include <iterator>

using namespace std;

static char *uuidValue = (char *)malloc(40);
static char *dtValue = (char *)malloc(20);

void set17();

int main()
{
    set17();
    return 0;
}

void set17()
{
    set<int> iset;
    int len=0;
    for(int i=0;i<10;i++)
    {
        iset.insert(i*i*i);
    }

    set<int, greater<int> >::iterator itr;
    len=iset.size();
    cout<<"iset' size="<<len<<endl;
    cout<<"Fisrt"<<endl;
    for(itr=iset.begin();itr!=iset.end();itr++)
    {
        cout<<*itr<<"\t";
    }

    for(int i=0;i<20;i+=2)
    {
        iset.insert(i*i*i);
    }
    cout<<"\n\nSecond"<<endl;
    cout<<"iset' size="<<iset.size()<<endl;
    
    for(itr=iset.begin();itr!=iset.end();itr++)
    {
        cout<<*itr<<"\t";
    }
    cout<<"\n\nFinished in set17() and now is "<<getTimeNow()<<endl;
    free(uuidValue);
    free(dtValue);
}   

 

Compile via

g++ -g -std=c++2a -I. h1.cpp -lpthread -o h1  -luuid

Run ./h1
