Hi,
I would like to recursively force to empty and delete a directory. As
such I would like to append the char *.
Here is the code:
char * directory = "Directory";
char * command = "rm -rf ";
How can I append the two to get: "rm -rf Directory"???
Following this, I would like to do the system command:
if(system(command) == 0)
{
printf("Successfully removed directory\n");
}
Thanks,
Marcia

只需包含< string.h>头文件，并使用strcat（）功能：
char * directory =" Directory";
char * command =" rm -rf";
strcat（命令，目录）;
system（命令）;
