In shell prompt if we try to cd .. ,it goes to previous directory.But in C program system(cd ..) does not work.
main() { system("cd.."); return 0; } You need to include the quotes.

main() { //if i run this program from $\root\vst\vst int i = System("cd .."); //now i=0, means success system("pwd"); //it shows $\root\vst\vst,not\\parent directory } In fact I have to write a command in program to change directory.System("cd..")could not solve my problem.

The 'system' call forks a new shell (I'm fairly sure), so it goes out, does the "cd .." and exits. Control returns and you are now in the 'old' shell and the 'old' directory.
You want to use the 'chdir' routine, not 'system'.
