You are required to: Declare a 4-by-5 array. The array should be initialized with the values as shown in Table 1. Display all the array values as per example in Figure 1. Display the maximum (highest) value as well as the maximum values row and column subscript as per example in Figure 1.

Then let the teacher fill the array by students IDs and courses marks for each student. And print the following: 1- Print the array. 2- Print the marks that are less than 50 (mark < 50)Rainfall StatisticsWrite a program that lets the user enter the total rainfall for each of 12 months (starting with January) into an array of doubles. The program should calculate and display (in this order): the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest amounts. Months should be expressed as English names for months in the Gregorian calendar, i.e.: January, February, March, April, May, June, July, August, September, October, November, December. Input Validation: Do not accept negative numbers for monthly rainfall figures. When a negative value is entered, the program outputs "invalid data (negative rainfall) -- retry" and attempts to reread the value. NOTE: Decimal values should be displayed using default precision, i.e. do not specify precision.
- Individual Exercise: Sieve of Eratosthenes O The Sieve of Eratosthenes is a technique for finding all the prime numbers up to a given last number. o It can be implemented as a program by using the algorithm (steps) given below. " Create a variable for the last number initialized as 100 etc. (e.g., int lastNumber = 100;) • Create a boolean array isPrime[] to keep track of which numbers up to lastNumber are prime. O The length of the array must be equal to lastNumber + 1 as the array indexes start from zero. o Note: The default value is false for all the array elements when a boolean array is created by using new. ' Set all the array elements beginning from index = 2 (the first prime number) to true. ' Outer loop: Repeat the following steps for each number num within 2 <= num <= lastNumber / num. o if isPrime[num] is true (meaning that num is prime as no factors exist for num): " Inner loop: Set the isPrime[] elements for all the multiples of num to false. O When the nested loop ends,…1. Create a struct called Booking that consists of a 3 digit flight number (e.g. 234), type of seat (E or B), the priceof a seat in economic class and the number of seats booked.Declare an array to store at least 30 Booking structs. (4)2. The user must be able to enter the information for a number of bookings from the keyboard. Ask whether abooking must be made (Y or N). If a booking must be made, a random 3 digit flight number must be generated.The user must be asked to enter the type of seat, the price per seat and the number of seats to book.3. Write code to display a numbered list with all the information of all the bookings. The price per ticket must bedisplayed with 2 decimal places. The output must be displayed with a heading and subheading 4. Write code to calculate and display the income earned per booking.
