Which of the following is most often a barrier to software migration? It’s easier to continue using an out-of-date software program as long as possible. It’s usually cheaper to upgrade software than it is to purchase a new product. It’s difficult to find new software that is secure enough to replace the old software. It’s not possible to keep old data when migrating to a new software program.

This program will store roster and rating information for a soccer team. coaches rate players during tryouts to ensure a balanced team. (1) prompt the user to input five pairs of numbers: a player's jersey number (0 - 99) and the player's rating (1 - 9). store the jersey numbers in one int vector and the ratings in another int vector. output these vectors (i.e., output the roster). (3 pts) ex: enter player 1's jersey number: 84 enter player 1's rating: 7 enter player 2's jersey number: 23 enter player 2's rating: 4 enter player 3's jersey number: 4 enter player 3's rating: 5 enter player 4's jersey number: 30 enter player 4's rating: 2

One subtask in the game is to roll the dice. explain why is roll the dice an abstraction.

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
