Regular Expression for Exact Extension for a Filename

Question

Hello All,

 

                   My question is i have following file names where it process based on the extension type using regular expression only.

 

 

  myname.c 

 myname.csi

 myname.ctr

 myname.hsi

 myname.h 

 myname.htr 

 

                          For the above strings if we apply regular expression the output should be

 

myname.c 

myname.h 

 

I want only file name with extension .c and .h only

 

 

Thanks & Regards,
