argv[1] will be the Mode integer.
argv[2]-argv[5] will be student info in the form [first_name, last_name, major, year].
argv[6]-argv[9], if present will be student info for a second student in the same form, and so on.
You will need to check argc to determine the number of students passed at runtime.
The fields are all strings (char[]), except year is a number (int)
