Comparison of the numeric values is performed in two
ways— whether or not one value is smaller/greater than
the other.
The size factor determines the comparison of two
numeric values, that is, the comparison of numeric
values is performed by determining whether or not one
value is smaller/greater than the other.
The comparison of character strings is performed by the
following procedure:
1. The value of one character is determined in
accordance with the table of ASCII character codes.
2. The value of strings having more than two characters
are compared as follows:
The value of comparison based on Rule 1 above should be
done on the first pair of characters, then on the
second, and so forth.
The string in which a character with a smaller code
value first appears is determined as smaller.
If either string ends but determination is not made
yet, the shorter one is regarded smaller.
