Write a c code to perform binary search. If the element is present print its next

nearest prime number. If the element is not present print -1.

EXAMPLE:

Input:

10 20 30 40 50 60 70 80 90 100

Search element-50

Output: 53 (50 is present so print 53(next nearest prime number))

Draw a UML class diagram. Create a CollegeCourse class. The class contains fields for the course ID (for example, “CIS 210”), credit hours (for example, 3), and a letter grade (for example, ‘A’). Include get and set methods for each field.

Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4).

Next, create a set method that sets the value of one of the Student’s CollegeCourses; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). Save the files as CollegeCourse.java and Student.java.
