Week 3 Class Activities

These activities are to make you practice more and are not graded! Implementation Guidelines:

• Students work in pairs or individually
• Each activity should take 10-15 minutes
• Encourage creativity and additional features
  

Problem 1: ATM

Create a program that:

1. Starts with a balance of 1000
2. Shows menu options (check balance, withdraw, deposit)
3. Updates balance after transactions
4. Prevents overdraft (balance < 0)
5. Continues until user chooses to exit

Problem 2: Count Characters

Create a program that:

1. Accepts a sentence from user
2. Counts total characters (excluding spaces)
3. Counts total words
4. Displays statistics (total characters excluding spaces and total words)

Problem 3: Grade Calculator

Create a program that:

1. Accepts assignment scores (tests, homework, projects) from users in the terminal

• where each of these assignment is calculated with it’s weighting factor
• For example, you are given that the weighting factor for tests is 20%, homework is 20%, and projects is 30%.

2. Calculates weighted average of the assignment scores
3. Show the current numeric grade which is the weighted average.
4. If the weighted average score is less than 50%, warn the student to prepare hard for the final exam in order not to fail the class
5. Calculates what score is needed on final exam for a potential desired grade of A which must be >=90 scores
6. Optional: Convert numerical grades to letter grades where >= 90 is A, >= 80 is B, >= 70 is C, >= 60 is D, and < 60 is F
