4 Printing Program Arguments

Here's the contents of arguments.cminor that prints each given program argument in its own line:

4.2 Possible Signatures of the Main Function

Here are possible signatures of the main function:

• If void return type is declared, the program implicitly returns exit code 0 to its caller.
• If int return type is declared, the main function must return an exit code explicitly by using a return statement.

The reason for requiring int return-valued main function to explicitly return a value is that this way the programmer cannot accidentally forget to return a value.
