对于控制台的Windows系统，可以使用system(dir)命令。控制台提供目录等信息。在cmd下阅读有关dir命令的信息。但是对于类unix系统，我不知道…如果执行了该命令，请读取bash命令。Ls不显示目录…

例子:

int main()
{
    system("dir");
    system("pause"); //this wait for Enter-key-press;
    return 0;
}

只是迟来的堆砌在这里，…

没有标准的解决方案，因为这些语言不知道底层文件系统，所以正如其他人所说，基于目录的文件系统的概念超出了c / c++语言的范围。

on top of that, you want not the current working directory, but the directory the program is running in, which must take into account how the program got to where it is - ie was it spawned as a new process via a fork, etc. To get the directory a program is running in, as the solutions have demonstrated, requires that you get that information from the process control structures of the operating system in question, which is the only authority on this question. Thus, by definition, its an OS specific solution.

在Windows上，最简单的方法是使用stdlib.h中的_get_pgmptr函数来获取一个指向字符串的指针，该字符串表示可执行文件的绝对路径，包括可执行文件的名称。

char* path;
_get_pgmptr(&path);
printf(path); // Example output: C:/Projects/Hello/World.exe

也许连接当前工作目录与argv[0]?我不确定这是否适用于Windows，但它适用于linux。

例如:

#include <stdio.h>
#include <unistd.h>
#include <string.h>

int main(int argc, char **argv) {
    char the_path[256];

    getcwd(the_path, 255);
    strcat(the_path, "/");
    strcat(the_path, argv[0]);

    printf("%s\n", the_path);

    return 0;
}

运行时输出:

jeremy@jeremy-desktop: ~ /桌面。美元/测试 /home/jeremy/Desktop/./test

If you fetch the current directory when your program first starts, then you effectively have the directory your program was started from. Store the value in a variable and refer to it later in your program. This is distinct from the directory that holds the current executable program file. It isn't necessarily the same directory; if someone runs the program from a command prompt, then the program is being run from the command prompt's current working directory even though the program file lives elsewhere.

getcwd是一个POSIX函数，所有POSIX兼容平台都支持它。你不需要做任何特殊的事情(除了在Unix上包含正确的头文件unistd.h和在windows上包含direct.h)。

由于您正在创建一个C程序，它将链接到默认的C运行时库，该库由系统中的所有进程链接(避免特别设计的异常)，默认情况下它将包含这个函数。CRT从来不被认为是一个外部库，因为它为操作系统提供了基本的标准兼容接口。

在windows上，getcwd函数已弃用，而支持_getcwd。我觉得你可以这样用。

#include <stdio.h>  /* defines FILENAME_MAX */
#ifdef WINDOWS
    #include <direct.h>
    #define GetCurrentDir _getcwd
#else
    #include <unistd.h>
    #define GetCurrentDir getcwd
 #endif

 char cCurrentPath[FILENAME_MAX];

 if (!GetCurrentDir(cCurrentPath, sizeof(cCurrentPath)))
     {
     return errno;
     }

cCurrentPath[sizeof(cCurrentPath) - 1] = '\0'; /* not really required */

printf ("The current working directory is %s", cCurrentPath);

这个问题是15年前问的，所以现在现有的答案是不正确的。如果你使用的是c++ 17或更高版本，现在的解决方案非常简单:

#include <filesystem>

std::cout << std::filesystem::current_path();
