void*memset(void* ptr,intvalue,size_tnum );memset(ptr,0xff,sizeof(ptr)); 使用memset初始化vector vector<int>vec(10,1);memset(vec.data(),0,vec.size()*sizeof(int)); #include<bits/stdc++.h> 需要注意的是:对于set和map而言,find并不是第一个满足条件的对象位置,而是其中的任意一个对象。
int> m; // 定义个空的map m,键是string类型的,值是int类型的 m["hello"] = 2; // 将key为"hello", value为2的键值对(key-value)存map中 cout << m["hello"] << endl; // 访问map中key为"hello"的value, 如果key不存在,则返回0 cout << m["world"] << endl; m["world"...
In this raw setup, the AMQP-CPP library does not do any IO by itself and it is therefore also not possible for the library to receive data from a socket. It is again up to you to do this. If, for example, you notice in your event loop that the socket that is connected with the...
问为windows设置Rcpp GSLEN每次使用Mongodb都要开启两个命令行，一个开启主流程程序，一个开启客户端程序。你是否想过更方便的操作方式？对的，那就是把主流程程序设置为Windows的服务，客户端程序也可以自定一个命令行脚本实现快捷启动。以下均以win8系统作为操作系统。
