Code a C++ function Circle_Circum() that takes one double argument that represents the

radius of a circle. The function should return the circumference of the circle.

Construct function prototypes that match the following descriptions:

i) ab () takes no arguments and has no return value.

ii) start() takes an int argument and returns a float.

iii) mk() takes two type double arguments and returns a double.

iv) func6() returns an int and takes three arguments. The first and third arguments are of

type double. The second argument is of type int.

v) func4() returns a char and takes one argument that is also of type char.

Write a program that calculates GPA

Arrays in main function

1.  A two dimensional array Grades[Number_of_students][Number_of_subjects] that stores the grades (0 ~ 100) of 6 students for 4 subjects.

2.  A one dimensional array Credit_hours[Number_subjects]

3.  A two dimensional array Grade_points.

 Grade_points [Number_of_students][Number_of_subjects] that will stores the grade points of each subject for 6 students.

4.  A one dimensional array GPA[Number_of_students] that stores the GPA of each student

Write the following Functions

a.  A function Enter_Grades() that takes the two dimensional Grades array.

b.  A function Enter_credit_hours that takes the array Credit_hours.

c.  A function Display_grades

d.  A function Calculate_ Grade_points that takes two arrays Grades and Grade_points.

e.  A function Calculate_GPA that takes three arrays Credit_hours, GPA and

GPA=(GP1*CH1 + GP2*CH2 + GP3*CH3 + GP4*CH4)/(CH1 + CH2 + CH3 + CH4)

generate random integers in the range [ LOW = 1, HIGH = 10000 ] and to store them in a vector < int > of size VEC_SIZE = 250. Then, sort the contents of the vector (in ascending order) and display it on stdout. To sort the contents of a vector, use the sort ( ) function in the STL. In addition to the main ( ) routine, implement the following subroutines in your program: • void genRndNums ( vector < int >& v ) : This routine generates VEC_SIZE integers and puts them in vector v. Initializes the random number generator (RNG) by calling the function srand ( SEED ) with the seed value SEED = 1 and generates random integers by calling the function rand ( ). • void printVec ( const vector < int >& v ) : This routine displays the contents of vector v on stdout, printing exactly NO_ITEMS = 12 numbers on a single line, except perhaps the last line. The sorted numbers need to be properly aligned on the output. For each printed number, allocate ITEM_W = 5 spaces on stdout.

Design a program using Java NetBeans (Console application). With the following enum class: public enum Day { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY } Create a second class called enumDayMood with a void method call telDayMood (). This method contain a switch case as follows: switch (day) { case MONDAY: JOptionPane.showMessageDialog (frame, "Mondays are bad."); break; case FRIDAY: JOptionPane.showMessageDialog (frame, "Fridays are better."); break; case SATURDAY: case SUNDAY: JOptionPane.showMessageDialog (frame, "Weekends are best."); break; default: JOptionPane.showMessageDialog (frame, “Midweek days are so-so."); break; } Create a method that will ask the user to enter a day of a week and the program should tell the mood of the day. If the user enter a wrong value the program should exit with 0.
