Write the C++ full main.cpp for the first screenshot titled, "Project 25.1" Then write full main.cpp mystring.h, and mystring.cpp for the second screenshot titled, "Project 25.2"

In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise.  A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks.  Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…

Answer this question please.

In C++, how does using pointers and references work in as parameters in a function of a class?   It is used a lot, and I dont really know how to use this as parameter in a function of a class, or in Polymorphism as well.

In C++,

C++ Attached is the question

Do in C++ And provide solution asapz   Do both parts

C++ LANGUAGE. I NEED COMPLETE CODE WITH ALL FUNCTIONS CLEARLY. Create a Book class with data members book title, author name, price, edition. You are required to implement the following functions using the Last In First Out data structure. •Constructor–for initializing the default values of a book•setData( )–for setting the data in the data members from the user•isEmpty( )–for checking whether stack of books is empty•isFull( )–for checking whether stack of books is full•push( )–for inserting abook in the stack. If the stack is full, you are required to ask the user whether he/she wants to insert even if the stack is full. If the user says yes, then re-size your stack to create a bigger stack. Also, check whether the book is already in the stack or not. If the new book is already in the stack, display the user a message stating the book is already in the stack.•pop( )–for removing a book from the stack•reverseStack( )–for reversing the order of the books in the stack. For example, if a…

Write in C++ Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min(), total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations: min() - returns the minimum value in the array sum() - returns the sum of all the values in the array average() - returns the average of all the values in the array You may assume that the array will be non-empty. Function specifications: Function 1: Finding the minimum hours studied Name: min() Parameters (Your function should accept these parameters IN THIS ORDER): arr double: The input array containing Alice's study hours per week arr_size int: The number of elements stored in the array Return Value:…
