Question

You designed a program to create a username using the first three letters from the first name and the first four letters of the last name. Usernames cannot have spaces. You are testing your program with a user whose name is Jo Wen. What step in the program plan do you need to revisit

Answer 1

The program needs to revisit the step where it combines the name to create the username.

Step-by-step explanation:

The step in the program plan that needs to be revisited is the one where the program combines the first three letters of the first name and the first four letters of the last name to create the username. Since the name of the user is 'Jo Wen', the program will only be able to use 'Jo' from the first name and 'Wen' from the last name. However, this will result in a username that is only comprised of two letters, failing to meet the requirement of using three letters from the first name and four letters from the last name.

Answer 2

The program needs to have logic that can handle last names shorter than four letters to create a proper username without spaces. The step to revisit in the program plan is to ensure usernames are generated correctly for names of any length.

Step-by-step explanation:

The student is inquiring about a step in a program plan they need to revisit when faced with a specific scenario. In this case, the issue arises when testing a username generation feature for a user with the name 'Jo Wen'. According to the design, the program should use the first three letters of the first name and the first four letters of the last name to create a username. However, the last name 'Wen' only consists of three letters, not four, which means the program's logic needs to account for last names shorter than four letters to avoid creating usernames with spaces or incomplete usernames.

To resolve this, the program might need a step that checks the length of the last name and adjusts accordingly, perhaps filling with a placeholder or simply using the available letters. Considering the username creation guidelines like using a first name or the first initial with the last name without spaces, the program code must be revisited to handle various name lengths appropriately.
