Question
javascript
Define a function, myIncludes, that accepts two parameters: an array and a searchValue.
myIncludes should return true if the searchValue is an element in the array. Otherwise, myIncludes should return false.
example
myIncludes([10, 20, 30], 20); // => true myIncludes(['apples', 'bananas', 'citrus'], 'pears'); // => false

- Randomize_it Write a function in C++ that takes an array as a parameter and then randomize that array, i.e. shuffles the position of the elements in random order. To randomize the array your function should perform random 100 swaps of any two elements in the array. Return the randomized array from the function.vector<int> randomize(vector<int> input){// code here}arrow_forwardint class Inventory { std::vector<Item*> m_Items; static unsigned int m_ItemsMade; void CreateItem() { std::string name = "Item " + std::to_string(m_ItemsMade); m_Items.push_back(new Item(name.c_str(), 100 * m_ItemsMade)); ++m_ItemsMade; } public: Inventory() { CreateItem(); CreateItem(); CreateItem(); } void Print() const { size_t* nSize = new size_t(m_Items.size()); std::cout << "_____INVENTORY_____\n"; for (unsigned int i = 0; i < *nSize; ++i) { m_Items[i]->Print(); } } }; GetValidatedInt(const char* strMessage, int nMinimumRange = 0, int nMaximumRange = 0); This function should first display the provided message to the screen then use cin to get an int from the user. Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear() and ignore() and try again (Note: the buffer still needs to be cleared even if this step was successful).

- Computer Science Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…arrow_forwardAn Iterator is an object that allows your code to produce the elements in a vector or other container one after the other, exactly once.

For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…arrow_forward
- palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage: >>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar'] >>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!")

So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces.
