Write a program using if else or switch cases only that prompts the user to input three (3) integers: MM, DD, and YYYY. For example, 07 26 1998. The program will print the number of days elapsed from 01 January of that year, i.e. January 1* is always 1 and December 31 is either 365 or 366, depending on if leap year or not. CASES: If a user inputs a valid int month, date, and year. Enter MM: 05 Enter DD: 18 Enter YYYY: 1995 Result: 138 days If a user inputs an invalid int month, date, and year: Enter MM: 02 Enter DD: 29 Enter YYYY: 1997 Result: INVALID

Write a program which: 1. prints all multiples of 5 between 5 and 50 inclusive and then 2. reads a number from the user and prints out if it is zero, above zero, or below zero

Write a program that asks the user to enter a number of seconds and works as follows: There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should convert the number of seconds to minutes and seconds. There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should convert the number of seconds to hours, minutes, and seconds. There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should convert the number of seconds to days, hours, minutes, and seconds.

In Java:  Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
