You're right on track here. The way I usually do this is as follows:

opendir DIR, "MainDir" or die "";
while( $file = readdir(DIR) )
{
  #do whatever you want to the file
}
closedir DIR;

One thing to note, this method includes directory names.

If you just want to grep for a string in all .cpp files in the current directory, try using globs (this is still magic to me, btw) like so: 

while( $file = <*.cpp> )
{
  #do something to the file
}
