Question
![/**
numUnique returns the number of unique values in an array of doubles.
* The array may be empty and it may contain duplicate values.
* Unlike the previous questions, you can assume the array is sorted.
*
* Your solution should contain at most one loop. You may not use recursion.
* Your solution must not call any other functions.
* Here are some examples
(using "==" informally):
*
*
*
*

- C++arrow_forward1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.arrow_forwardMULTIPLE FUNCTIONS AND RECURSIVE FUNCTIONS HANDS-ON use #include<stdio.h>arrow_forward

You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.arrow_forward
- 8arrow_forward17: recursion.cpp) Write two recursive integer functions. The first function should calculate factorials using the definition 0! = 1 and n! = (n-1)! x n. In addition, if n is too large it should be able to detect integer overflow before it happens. The next function should calculate the greatest common factor (gcf) of two numbers. If the second number is zero, then the gcf is the other number. Otherwise, the gcf of a and b is the same as the gcf of b and a mod b.arrow_forwardC++ Coding: Arrays Implement a 4x4 two-dimensional array of integers. Use a nested loop to populate the array with values 20 to 35 inclusive. Use a nested loop to output the array as a grid. Use a single loop to output all elements in the second row. Use a single loop to output all elements in the third column. Use a single loop to output all elements in the first diagonal (r==c). Use a single loop to output all elements in the opposing diagonal.
