Please have the solution in a file named launch.c
  a) Break it up into multiple source files. You will probably want to use a Makefile to compile it, but this will not be turned in, so you are free to compile it by hand if you want. The defined constants LINE_LENGTH and MAX_ARGs, plus the arrays command and argv should be declared in a file called globals.h. The function launch must be in a file called launch.c. It would be sensible to put other functions in other source files, but this is not required. It would be sensible to build your project in its own project directory, but this is not required. Each sourc file should have include directives for the files it relies on, and none others. For example, don't write # include  in a file that does not rely on any of the definitions in the standard I/O library Each source file should have header comments that indicate what it is, its provenance, etc.  a) Break it up into multiple source files.
