La universidad asignará becas por sistema de un porcentaje que se descontará de su inscripción de acuerdo al promedio del alumno en el semestre anterior. Si un alumno tiene un promedio mayor o igual a 9, la beca es del 20%, si su promedio no es mayor a 9 pero si es mayor o igual a 8 la beca será del 10%, si su promedio no es mayor o igual que 8, pero si es mayor o igual a 7 la beca será del 5% y si su promedio no es mayor a 7 no tendrá beca. Utilizar una función que reciba como parámetro el promedio del alumno y determine el porcentaje de la beca que se asignará. Programas en c#

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.
