Command-line arguments in C Programming Language 在C编程语言中,命令行参数可以用来向程序传递参数。在命令行中,当您键入命令时,可以在后面添加参数。当程序运行时,它可以读取这些参数并根据它们采取不同的操作。 传递命令行参数 在C语言中,可以使用main函数来访问命令行参数,用以下方式声明: ...

2、getchar()从键盘输入缓冲区读取最后一个字符,若按过回车,则最后一个字符应当是‘\n’ ,可以将次作为命令行参数输入完毕的标志 代码如下: 1#include <unistd.h>2#include <string.h>3#include <stdio.h>4#include <wait.h>5#include <stdlib.h>6#defineMAX_LINE 8078intmain(void){9char*args[MAX_...
