okay, so I can assume that the arguments will be accessed under the alias arg0, arg1, .... and not under any other name correct? but wouldn't this contradict the statement where identifier names can only include lowercase alphabetic order?

Technically they're not considered "identifiers" just "variables". So, in other words, they're an exception to the rule. As stated in the project description: "8.the variables arg0, arg1, and so on, provide access to the program's command-line arguments which provide real-valued number."
