Question

A string internet domain is read from input and represents an internet domain. The internet domain has three fields, each separated by a character '.' Output the last field of the internet domain. End with a newline.

a) Input the internet domain and display the second field.

b) Input the internet domain and display the first field.

c) Input the internet domain and display the third field.

d) Input the internet domain and display the entire domain.

Answer 1

To output a specific field of an internet domain, the domain is split using the '.' delimiter, and the specific part is selected and printed depending on whether the second, first, third field or the entire domain is requested.

Step-by-step explanation:

To extract the desired field from an internet domain, one can split the domain string into parts using the period character as a delimiter and then output the required field.

Example Input and Outputs

• Second Field: Given 'example.com.net', the second field is 'com'
• First Field: Given 'example.com.net', the first field is 'example'
• Third Field: Given 'example.com.net', the third field is 'net'
• Entire Domain: Given 'example.com.net', the entire domain is 'example.com.net'

To accomplish this in code, you would use a language-specific function, such as split() in Python, that divides a string into an array of substrings based on a delimiter. Then, access the appropriate element of the array which represents the required field. Remember to include a newline character at the end of the output as specified.
