Write a C program myfind whose behavior resembles that of the system command find.

myfind accepts the following parameters:

$ myfind filename startpath 

where:

filename is a substring that is matched against each filename in each directory that myfindinspects. If a file name matches filename or if the substring filename occurs within a file name, the name of that file is printed.

startpath is an optional parameter that specifies the directory where myfind must start the search. If this parameter is not specified, myfind starts in the current directory.

For each file whose name is a match, myfind must print its name and its mode.

For each directory in which myfind finds a match, it must print that directory's full path.

Test myfind using various directories on your computer attempting to match full and partial file names. Below is a typical output produced by myfind
