Part 2: Processing Strings (Individual work)

Processing user-entered data to follow a specific format is a common task. Often this involves using string functions to manipulate a set of input strings.

Create a MATLAB script named namephone.m and place these lines of code at the beginning:

name  = input('Enter your first and last name: ','s');

phone = input('Enter your area code and phone number: ','s');

Tasks

Here are useful string functions:  length, strcat, strtrim, lower, upper, strcmp, findstr, strrep

As you work through this, test your code with different badly formed name and phone strings.

• Assume the user enters his or her name as a single string like this: FirstName LastName. To keep it simple, you may also assume the user is not entering just a single name or more than two names. There will always be at least one space character between the two names.
  • Separate the full namestring into two, separate string variables. Store the first name in a variable named FirstName, and store the last name in a variable named LastName.
  • Remove all leading and trailing spaces from both of the new strings.
  • Example:  name is '  kAthY JonES '            FirstName --> 'kAthY'        LastName --> 'JonES'

Show a sequence of MATLAB commands to do this in the box below.

• It is possible that the user entered his or her name in a mixture of uppercase and lowercase characters that does not make sense.
  • Modify the FirstName and LastName strings so that only the first letter of each is capitalized.
  • Example:  FirstName --> 'Kathy'   LastName --> 'Jones'

Show your commands below.

• Suppose the program requires the user’s name be put in last name first and first name last order.
  • Construct a new string named UserNamein this order: LastName, FirstName  (comma is needed)
  • Example: UserName ---> 'Jones, Kathy'

Show the commands need to create UserName.
