Write a modular program that accepts up to 20 integer test scores in the range of 0 to 100 from the user and stores them in an array. Then main should report how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function to help it.

Create a function named "onlyOdd".The function should accept a parameter named "numberArray".Use the higher order function filter() to create a new array that only containsthe odd numbers. Return the new array.// Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];

Write a function named swapFrontback that takes as input an array ofintegers and an integer that specifies how many entries are in the array. Thefunction should swap the first element in the array with the last elements inthe array. The function should check if the array is empty to prevent errors.The header file for the swapFrontback() is:swapFrontback.h:double swapFrontback (int [] arr,int size);Write a driver (main.c) to test your function with arrays of different lengthand with varrying front and back numbers. Print the array elements beforeand after the swap in the main.c.Sample Run: Original Array: 1 2 3 4 5 6 FrontBack Array: 6 2 3 4 5 1

C++ Write a function named “checkInvalidHours” that accepts an array of PaySubobjects and its size. It will go through the array and check for invalid hours(negative values). If it is negative, it will reset the hourly payrate to 0. It willreturn how many PayStub objects that it has reset the payrate to 0.Please show you would call and test this function.

You are designing a function that will manipulate an array of integers. It needs to work for arrays of any length. What is the minimum number of parameters your function will have?

In C++  please ! Write a Program that: Initializes an interger array size of 10 with random intergers in range [10,30]. Use a function named 'initialized_array' to acheive that. Determine if all array elements are distinct from each other or not.Use boolean function  named 'distinct_elements' to achieve that function 'distinct elements,  if the elements in the array are duplicate print out, elements are duplicate if not print out array

8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.

Write a function that accepts (but does not read) a 2D array of marks and length (the number of students).  The function returns a one-dimensional array with the total marks of the students and the class average. Write the declarations, and show the call to the function from function main.  Assume all input and output take place in function main, not in this function, and you do not have to write the code to read in the data.  Show the main program and the function call.   const int NUM_STUDENTS = 35; const int NUM_ASG = 5; //Purpose: To calculate the total marks for 35 students and the class average //PreCondition: marks is a 2D array already filled with 5 marks for each student //                             length is the actual number of students with marks //Post Condition: total is a 1D array which is the total of the 5 marks for each student avg is the class average of the total array (for length number of students) void TotalAverage(const double marks[][NUM_ASG], int length,…

in c++ Write a function named “countTheSameAsLast” that accepts an array of pointers to Name objects and its array size. It will go through the array and return how many elements (int) in the array are the same as the last element and whether the first and the last elements are the same or not (bool). Please note that the objects pointed by elements in the array can be either Word or Item objects. Please show how you test with the list of mixed objects.
