In C# Suppose variable nums contains a list of integers.List«Integer> nums = Arrays.asList(1, 1, 2, 3, 4, 1, 3, 2, 4, 3, 3, 1);var nums = new List«int> { 1, 1, 2, 3, 4, 1, 3, 2, 4, 3, 3, 1 }Using Java Stream API *or* LINQ, write a short code that prints the following.For each section indicate the platform (whether the solution is given in Java orC# LINQ).A) Print all numbers.B) Print the sum() of the numbers.C) count how many times number '1' appears in the list.
In C, write a function that gets 3 pointers int* a, int* b, int* c, and rotates the values in their addresses to the left. That is, a gets the value of b, b gets the value of c, and c gets the value of a. void rotate3 (int* a, int* b, int* c); For example, if we have int x=1, y=2, z=3, then after calling rotate3 (&x, &y, &z) we should have x==2, y==3, and z==1. if we have int x=7, y=1, z=6, then after calling rotate3 (&x, &y, &z) we should have x==1, y==6, and z==7.
Instruction: Answer question 4 (a,b & c) only (1) Create a C++ project for your assignment 3, with the name format prescribed in the Information section. Add a source file and name it SwapCount. In this file, write the C++ program that will perform the tasks specified in question 2.(2) Declare and implement a function called sortSwapCount that passes three parameters, the array, the size and the reference of proportion, and returns the count. The functiondeclaration is int sortSwapCount(int data[], int size, double& proportion) (i) The function sorts the integers in data[] in ascending order using the bubble sort method. The purpose is to count or determine the number of exchanges (swaps) made by the bubble sort algorithm. (ii) The expected number of sorting swaps (expectedSwapCount) is size * (size - 1) if the array was unsorted. Calculate the proportion of the array status by first converting (or casting) the integers, swapCount and expectedSwapCount into floating-point,…
3.) Write a C++ program that will prompt the user for the size of a list of integers. Your program will 1. dynamically allocate an array of that size and allow the user to enter the values. 2. Your program will then go through the list and copy all even numbers to another dynamically allocated array. The functionality of 1 and 2 need to be accomplished by separate functions. 4.) Redo question number 3 with these changes. Instead of dynamically allocating an array to store the data, your program will will an STL array. Even numbers will also be copied to an STL array. The input of the data and copying of even numbers will require the program to start at the beginning of the array and walk thorugh the values to the end. This must be done using iterators.
Create a program in C as follows:- Declare four floats as a1, a2, a3 and a4- Create a menu as follows:Option T to ask the user for and assign values to each of a1, a2, a3, and a4.Option V to call a function named cat that has four pointers of type float as parametersand no return. The function will sort, in ascending order, the values in a1, a2, a3 and a4.Option B to call a function named mouse that has four pointers of type float asparameters and no return. The function will sort, in descending order, the values in a1,a2, a3 and a4.Option K to call a function named dog that has four floats as parameters and no return.This function will print to the screen each of the values in a1, a2, a3 and a4 in aformatted manner (right justified with a field width of 12).Ex:a1 = 23.65a2 = 99.22a3 = 1.56a4 = 0.50Option X to exit the program.
Code language Java 1, Add a print statement to say “Multiplication Table” and then prompt theuser to enter an integer. Your program should then prints “times table” for thenumbers from 1 to the given integer (inclusive). That is, for input n, you would printa table of n rows (lines) each with n columns, where the cell at row i and columnj contains the value i × j. You do need separate rows, but don’t worry about thecolumns lining up nicely yet. 2. Add a print statement to say “Prime Testing”.Using the integer entered by the user above, print out all the prime numbers between2 and the number squared. E.g., if the user types 12 for the multiplication table part,you should print all the prime numbers that are not larger than 144.All integers are either prime or composite. A prime number is one that has no integerfactors other than itself or one. Examples are 2, 3, 5, 7, 11, 13, . . .. A compositenumber, by contrast, has multiple factors. Examples are 4, 6, 12, 15, 18, 21, . . ..Testing…
Write a program in c that will read an arbitrary numbers of proverbs from the keyboard and store them in the memory that's allocated at run time(pointers). The program should then output the proverbs ordered by their length, starting with the shortest and ending with the longest **for arbitrary no of proverbs (the program should display a prompt every time it runs and ask the user the NUMBER of proverbs he/she wants to enter **AND then the user will enter the proverbs according to the number he provided first and then the entered proverbs are stored in pointers as mentioned above) **plz provide the code in text base format too instead of only pictures
