Conversion result Double word
Explanation:
1. The IP address of the string type in S is converted into the IP address of the integer type, and
the conversion result is stored in D.
2. The operand S occupies eight devices.
3. The IP address of the string type in S is divided into four sections. These sections are
separated by “.” (16#2E), and there are three characters in every section.
4. The value converted from the characters in every section of the IP address of the string type in
S can not be larger than 255.
5. If S is a string, there are not necessarily three characters in every section of the IP address of
the string type. For example, users can enter “192.168.0.1” instead of “192.168.000.001”.
