Anyone can explain me please? why this is true???

Answer 1

Because when comparing strings it does so alphabetically.

Answer 2

strings are compared according to their position in the ascii collating sequence

ascii table:

Answer 3

forget about letter ook
they are the same

every letter has a number according to its alphabetical order
a=1
b=2
c=3
d=4....
.
.
.

and those numbers used to compare strings
"c" >"b"
"ook" ="ook"
"cook" > "book"

hope that helps😇
