I think there are a lot of us here who could write that in C in a matter of a few minutes, but you'd not learn anything if any of us did. Thus, I'll offer a few pointers:
  • look at using argc and argv to get the file name from the command line
  • Use the stat() function to determine whether the file exists.
  • Use the unlink() funciton to remove the file if it exists

Use the man command to determine the calling parameters and how they work. Have fun -- C is a wonderful language.
