C++编程中,头文件范围更广,如`algorithm`用于通用算法,`iostream`负责输入输出操作,`vector`和`set`是动态数组和集合容器,`exception`用于异常处理等。当你需要在C/C++程序中使用这些特定功能时,务必在代码开头包含相应的头文件。例如,如果你计划进行数学计算,`#include `就是必不可少的。对于C++...
include<stdio.h>是在程序编译之前要处理的内容,称为编译预处理命令。编译预处理命令还有很多,它们都以“#”开头,并且不用分号结尾。stdio.h是头文件,标准输入输出函数库。头文件是扩展名为 .h 的文件,包含了 C 函数声明和宏定义,被多个源文件中引用共享。有两种类型的头文件:程序员编写的头文...
