In C please please make sure it passes the $5$ cases on the first and second pic that's all I need. Third time posting this question still no use.

Here is the project :

$-$Name your program project$5\_$valid.c$.$

$-$Input characters are command line argument.

$-$Character handling library functions in ctype.h are allowed.

$-$The program should also check if the number of arguments on the command line is greater than $2($including $./$a$.$out as one of the arguments$).$ If the number of arguments is not greater than $2,$ the program should print "invalid number of arguments".
