code::blocks配置頭文件#include

萬用頭文件#include<bits/stdc++.h>，包含了<queue>,<vector>,<string>,<algorithm>,<iostream>等等各個競賽中經常使用或不經常使用的頭文件，可謂省時省力，競速必備。現在已被大部分oj所支持。面試時大部分的判題系統也親測可用。但有的編譯器卻不可以使用這個頭文件。本文以code::blocks爲例，教你們配置此頭文件

1.尋找code::blocks的gnu gcc編譯環境

setting->compiler->ToolChain executables

能夠看到他借用了dec的編譯環境。若是你的code::blocks沒有編譯環境，也可在linker setting中引入

2.找到include下的bits文件夾

嘗試着打bits時發現以下細節

 

原來原本就有一個bits文件夾！咱們隨便在已經找到的編譯環境下找找

看到文件名，跟以前編譯器的提示同樣。就肯定是這裏沒有錯誤了

3.新建stdc++.h文件，並放入bits

而後你新建一個stdc++.h放進去就能夠了。stdc++.h內容以下
