Look at exec and system, these are probably the functions you would use, they both have ways of letting you know a file was not there to be executed, or at least, that the command failed...

if they are always going to give you full path to a command you can use -f filename and -x filename to make sure it is a file and that the user can execute it...

this sounds a bit like a homework assignment...
