Homework 1 1. Write a program that tells the user a letter grade based on a percent score that the user provides 2. Write a program that gets an integer from the user and then reports whether the number is odd or even. Make sure that the number is positive. Hint: the % operator (called modulo) gives the remainder of division. Consider the following code snippets: 5 % 3-2 # 3 goes into 5 once with 2 left over 6 % 3--0 # 3 goes into 6 twice with 0 left over use it to determine the number's oddness/evenness 3. Write a program that prompts the user to enter a number between 1 and 5 (inclusive). Your program should print the corresponding Roman Numeral or print an error message for invalid input This homework is due Tuesday the 11th of September in class
