The Assignment
1) Adelphi University classifies students according to credits earned. A student with less than 30 credits is a Freshman. At least 30 credits are required to be
a Sophomore, at least 60 to be a Junior, and at least 90 to be classified as a Senior. Write a program that calculates class standing from the (whole) number of credits earned. Have your program return an appropriate message if a negative number is inputted.
2) Write a program that takes in an int. The program should print out if the int is even or odd, and if the int is positive or nonpositive.
3) Write a program that uses a while loop to determine how long it takes
for an investment to double at a given interest rate. The input will be an
annualized interest rate, and the output is the number of years it takes an
investment to double. Note: The amount of the initial investment does not
matter; you can use $1. (Have the program return a whole number of years, so whether the doubling time is 15.2 years or 15.7 years, your program should return 16 years either way.)
4) Write a program that continuously prompts the user for a line of text and prints it, until the user types "The end". (Hint: Use a while loop.)
