• code::blocks配置头文件#include<bits/stdc++.h>


    万用头文件#include<bits/stdc++.h>,包含了<queue>,<vector>,<string>,<algorithm>,<iostream>等等各个竞赛中常用或不常用的头文件,可谓省时省力,竞速必备。如今已被大部分oj所支持。面试时大部分的判题系统也亲测可用。但有的编译器却不能够使用这个头文件。本文以code::blocks为例,教大家配置此头文件

    1.寻找code::blocks的gnu gcc编译环境

    setting->compiler->ToolChain executables

    可以看到他借用了dec的编译环境。如果你的code::blocks没有编译环境,也可在linker setting中引入

    2.找到include下的bits文件夹

    尝试着打bits时发现如下细节

    原来本来就有一个bits文件夹!我们随便在已经找到的编译环境下找找

    看到文件名,跟之前编译器的提示一样。就确定是这里没有错误了

    3.新建stdc++.h文件,并放入bits

    然后你新建一个stdc++.h放进去就可以了。stdc++.h内容如下
