Main Program:The main program will read in and print three integer values, representing SAT scores. Then the main program will call the method isitavalidgroup() to determine whether or not this group is valid. In either case, the main program will print the result of the method call (and add to the appropriate counter – discussed below).
In more detail: If the method isitavalidgroup() says this is a valid group, the main program will print a message, add to the counter of valid groups, and call the method classify().
However, if isitavalidgroup() says the group is not valid, the main program will print a message, add to the counter of invalid groups, and go back to read the next group.
Be sure to skip a few lines on the output sheet between groups. (And somewhere add to the counter of total groups.)
The main program will continue this process for the entire set of data. When the main program runs out of groups of three values (you must decide when this occurs), print the final values…

8. Consider the following equation for the sum of a finite arithmetic series:
S, = n(a, ta
where n is the number of elements in the series, a is the first element of the series, and
a, is the last element of the series.
Write a method that returns the sum of the elements stored in the array in 8 above.
The array must be passed to the method as an argument. Your solution should
implement the equation for the sum S.

The main program will call a method to determine if these three scores are all valid--valid means in the range from 200 to 800, including both end points, and is a multiple of 10 (ends in a 0). If the scores are all valid, the main program will call a method (which will itself call other methods) to classify the group of three scores in various ways. The main program will repeat this process for the entire set of data, then print some counters. Main Program:The main program will read in and print three integer values, representing SAT scores.

Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the…arrow_forward
