To execute a command in the same cmd.exewindow where your C program is running:
要在cmd.exe运行 C 程序的同一窗口中执行命令：
#include <stdlib.h>
.
.
.
system("dir C:\");
To launch a separate windows, you need to call cmd.exe:
要启动单独的窗口，您需要调用cmd.exe：
system("cmd.exe /c dir c:\");
(Note: I have not tested this one);
（注意：我没有测试过这个）；
