Go back to Previous Directory in Linux using a C program

The chdir function changes the directory, but it does not change the original directory.

For example:

$ pwd
  ~/home/loganaayahee
 $ cc chdir
 $ ./a.out ~/Desktop
 The directory change sucess and the current dir is ~/Desktop
 $ pwd
 ~/home/loganaayahee

The shell does not change the directory. What is the reason? so I do change the original directory what i do?. what purpose usedto the chdir() function?

It changes it in the environment of the new process. No process can change the environment of its parent. – cnicutar Jan 07 '13 at 06:50
