@Mahesh.
Check chap length it should be 6. Then chap? will work.
You used chap* for this length not matters.

It's working correctly when I used char* but when I used char it occurs an error as.
cp: cannot stat 'chap??': No such file or directory.
How to solve this?

The question asking for progs directory without even mentioning the location of it, then why the answer 'D' is not correct while 'A' is correct. Can anybody elaborate?

@Chet.
?? means any two characters. If you used char* it will show files whose name starting from char like, charcoal, character etc.

If there is directory "progs" then you can not create a file with the same name. When you want to copy multiple files to a single location. Then you can only copy it to a directory, not a file.

Its not the string in the file. But the name of the file itself.
