What is the problem? You should get back 0 or -1 from chdir... then use errno to find out what the actual error code should be. This will give an idea as to what is happening.

yes i want any result from chdir

OK - You should set a result, e.g. int result = chdir(str) and check the value of errno if result is -1. The errno is just another integer that you can output to the console. For more detail on which error values are returned, consult http://linux.die.net/man/2/chdir

            scanf("%5[^\r]", str);

Two problems:
1) You cannot set str1[400] - str1 is an array from 0 to 399,
2) You cannot set a character from an entire string - you need to use strcpy instead

3) Also, don't update your problem as a solution.
