Can you add the following to the provided code?

• Add a function to get the student name
• Add a function to assign a letter grade called from Main.
• The letter grade is then passed to the displayResults function
• Hint: This means you will need to add an extra parameter to the displayResults function
• Ask the user if she wishes to repeat the program for another student and either loop or end the program.

Don't use global variables.Pass data through function parameters.
