Questions

1. What is the largest unsigned and signed number that can fit in a single byte?

One byte is equal to 8 bits. Each bit can store two values, either 0 or 1. So the maximum number of different numbers can be 2⁸. That is 256.

Unsigned numbers start from zero, so the largest unsigned number is 255.

Signed numbers are somewhat more complicated. Come back later for the explanation!
