Question

Most versions of Pascal allow variable names to consist of eight letters or digits with the requirement that the first character must be a letter. How many eight-character variable names are possible?

I know that there are 2^7 ways to arrange letters and numbers in the remaining seven spots, what else is needed?

Answer 1

multiply by the number of letters in the alphabet :)

Answer 2

Would I also multiply by the number of digits in order to cover numbers, as well?

Answer 3

there are 26 letters and 10 digits including zero
You can repeat I assume
like
A1111111
or
B2222222
or
AAAAAAAA
so I would say each of the last seven could be any of the 36
so 26 * 36 * 36 * 36 * 36 * 36 * 36 * 36

Answer 4

Alright. That makes sense. Thank you!
