Create a function which receives a pointer of array as a parameter and calculates the sum of prime

numbers and sum of non_prime numbers in that array. Then compares them to find out which one is

larger (sum of prime or sum of non_prime). Return both sum of prime and sum of non_prime numbers

also and print those in the main function.

Create a function to compare the elements of 2 arrays. Function should receive two pointers to an array

and then check if the elements are same in both arrays or not. If both arrays are same return true,

otherwise false.

Suppose you want to send a message to your friend but don’t want others to understand that message.

So, you have decided to encrypt the message.

Now, suppose the message is in a string variable called MSG. a) You have to encrypt the message and

c)         Method averageLow: This method calculates and returns the average low temperature of the year.

d)         Method indexHighTemp: This method returns the index of the highest temperature in the list.

Store the details of the following 3 flights in a 2-dimensional tuple:

Flight number Destination Departure time

EK004 London 12:30

EK012 Paris 14:00

EK052 Male 16:15

Create a function called checkFlightNumber which accepts a flight number as an input parameter. This function will check if the flight number is found in the tuple which contains the flight details and return TRUE of found or FALSE if it is not.

Your program should keep asking for passengers’ (loop)details until the user enters n to stop. The program should first ask for the passengers’ flight number and use the checkFlightNumber function to check if it is valid or not. If checkFlightNumber returns FALSE, your program will print an appropriate error message and ask the user to try again. However, if checkFlightNumber returns TRUE, your program should ask

the user to enter the following passenger details:

1.Name

2.Date of birth

3. Passport number
