The goal of this coading exam is to quickly get you off the ground eith the array method every().there is a selection going on for the civil service sector candidates have to participate in x number of events and, the condidates who score more than 75 points in every event will be selectedgiven candidatesList as input,it contains objects with the name of the condidate and an array consisting of points achieved in each event by the condidate.filter the condidates who have scored more than 75 points in every event

log the array consisting of the names of the selected candidates in the console

i/p:the i/p will be a siongle line containing an array with names of the selected candidates

constraints:keys of objects should be given in quotes

input:

[{'name':'Blake Hodges','points':[76,98,88,84]},{'name':'James Anderson','points':[0,98,12,33]},{'name':'Matthew Norton','points':[89,67,83,93]}]

output:

['Blake Hodges']

JamEx Limited requires a program to calculate and print the commission received by a salesperson. The program should process an undetermined number of salespersons and appropriately terminate by a predefined input. The commission rate is based on two factors, the amount of sales and the class to which a salesperson belongs. The input will be the salesperson number, sales amount and class. The commission rate will be based on the following criteria:

Class=1

If sales is equal to or less than $1000, the rate is 6 percent.

If sales is greater than $1000 but less than $2000, the rate is 7 percent.

If the sales is $2000 or greater, the rate is 10 percent.

Class=2

If the sales is less than $1000, the rate is 4 percent.

If the sales is $1000 or greater, the rate is 6 percent.

Class=3 The rate is 4.5 percent for all sales amount

Class=any other value

Output an appropriate error message.

 5. “OptionB” Method 

Create a method called “OptionB” that will print the conversion from miles to kilometres by calling “MilesToKilometers” method (defined in the item #6 below) starting at 10 miles up to 100 miles in increments of 10. Show the result on a table in the console. 

6. “MilesToKilometers” Method 

Create a method called “MilesToKilometers” 

• • Name: MilesToKilometers 
• • Parameter: o A double representing the miles distance 
• o A double representing the kilometers distance - this should be an "out" parameter 
  
• • Returns: Nothing 
• • Displays: Nothing 
• • Task: Calculates the conversion from miles to kilometers. The converted kilometer is returned as an "out" parameter

 Write a program to perform the function of a Simple Interest Calculator.

Task 4 

Write a program that does the following for 15 

students:

 Reads in 3 marks for each student (you 

need to ensure that only valid marks 

between 0 and 100 are processed) – your 

prompt message to the user should 

indicate which number is being requested 

(see example image of output)

 Calculates and displays the highest mark 

for each student.

Finds and displays the highest mark in the class.

1. Input five decimal numbers in one line.
2. Print out the decimal numbers in one line, separated by spaces, and make sure you only print up to 1 decimal place.
3. Add the first four decimal numbers and check if their sum is greater than the fifth decimal number. Print out "Yes" if they are.
