“map” template class: Type name for “map” of type “KeyType” elements to “T” elements is “map<KeyType, T>” or “map<KeyType, T, Ordering>” The “Ordering” is used to sort the values by using the key value. If no “Ordering” is given, the ordering used is the binary operator “<”. The library header for “map” is “<map>”. It places the definition in the “std” namespace. Defined type for “map” is given below: “key_type” is used to represents the type of the key values. “mapped_type” is used to indicate the type of the values mapped to. “size_type” is used to represent the type of the size. The iterators are used in the “map” template class is “iterator”, “const_iterator”, “reverse_iterator” and “const_reverse_iterator”. The “map” template class uses the pair template class. The pair template is used to store the association between the key and a data item. Example: “map<string, int> numMap;” Using the above example, user can add a mapping from “c++” to the number “8” by using “[]” operator. Example for the above statement is “numMap["c++"] = 8;”.

Chapter 18.2, Problem 14STE

Program Plan Intro

“map” template class:

Type name for “map” of type “KeyType” elements to “T” elements is
“map<KeyType, T>” or “map<KeyType, T, Ordering>”

The “Ordering” is used to sort the values by using the key value.

If no “Ordering” is given, the ordering used is the binary operator “<”.

The library header for “map” is “<map>”.

It places the definition in the “std” namespace.

Defined type for “map” is given below:

“key_type” is used to represents the type of the key values.

“mapped_type” is used to indicate the type of the values mapped to.

“size_type” is used to represent the type of the size.

The iterators are used in the “map” template class is “iterator”, “const_iterator”, “reverse_iterator” and “const_reverse_iterator”.

The “map” template class uses the pair template class.

The pair template is used to store the association between the key and a data item.

Example: “map<string, int> numMap;”

Using the above example, user can add a mapping from “c++” to the number “8” by using “[]” operator.

Example for the above statement is “numMap["c++"] = 8;”.

Unit 1 Assignment 1 – Loops and Methods (25 points) Task: You are working for Kean University and given the task of building an Email Registration System. Your objective is to generate a Kean email ID and temporary password for every new user. The system will prompt for user information and generate corresponding credentials. You will develop a complete Java program that consists of the following modules: Instructions: 1. Main Method: ○ The main method should include a loop (of your choice) that asks for input from five users. For each user, you will prompt for their first name and last name and generate the email and password by calling two separate methods. Example о Enter your first name: Joe Enter your last name: Rowling 2.generateEmail() Method: This method will take the user's first and last name as parameters and return the corresponding Kean University email address. The format of the email is: • First letter of the first name (lowercase) + Full last name (lowercase) +…
