cstdio (cstdio和stdio.h)
cstdio是将stdio.h的内容用C++头档案的形式表示出来。stdio.h是C标準函式馆中的头档案,即:standard buffered input&output。提供基本的文字的输入输出流操作(包括萤幕和档案等)。由于C语言并没有提供专用于文字输入输出的关键字,所以该库是最普遍的C语言程式载入库。
cstdio 和 stdio.h是有差别的,并不是同样的档案。
基本介绍
中文名:cstdio别称:C语言所属:标準C++类别:计算机使用方法
stdio.h是以往的C和C++的头档案,cstdio是标準C++(STL),且cstdio中的函式都是定义在一个名称空间std里面的,如果要调用这个名字空间的函式,必须得加std::或者在档案中声明using namespace std。#include
