I'm coding for the UNIX environment using the C++ language.

So I'm supposed pipe one function with another function that displays a line that contains a certain string. (filecount function and filedisplay function)

The first function with a given argument that contains a directory, it recursively finds all files and directories and returns how many files and directories are in the given directory.

So if I type in filecount /usr/ | filedisplay -d it should display only how many directories there are.

And if i type in filecount /usr/ | filedisplay -f it should display only how many files there are.

So far I'm finished with filecount but I don't know how to write filedisplay.

If I run only the file count it displays both the information about # of directories and files in two lines.

Could you help me with this problem may be using regex?

fileDisplay is another cpp file that will be used for Pipe
