Question

Hello. I have a C assignment. I have been too sick couple of days I was not able to complete this. Can you possibly write this out. I am willing to give you a lot of credit if you could help me out. Thanks.

Your task is to implement a program that takes command-line arguments and checks whether each argument matches a particular pattern. The pattern to check is determined by a command-line flag -a, b, or -c, where the default mode is a. The patterns for each flag are described below. By default, your program should print "yes" for each matching argument and "no" for each non- matching argument, each on a separate line. If the t flag is provided, then your program should instead print nothing for non-matching arguments and it should print a converted value for each matching argument. Each pattern mode has an associated conversion, as described below At most one of a, b, or c will be provided. A -t flag can be provided before or after any of b, and -c. All flags (i.e,. up to two of them precede other command-line arguments. A non-flag argument never starts with All arguments are in ASCII

//Function to check the pattern starts with -a.

//argv[0] is the name of the program and rest all contains the command line arguments.
//argc is the number of arguments including name of the program.
