- 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,…Write code to perform write() read() append() through system calling in a single program in Windowswrite c++ program text editor cut copy paste (using stack) include clipboard history (history of copy saving by stack and calling history of copies)
- Question 5 Write a program that reads 10 characters from the keyboard and then print the characters to the screen in reverse order. Use a loop, the keyboard interrupt 21h, the console interrupt 10h and the svstem stack to Implement your solution Full explain this question and text typing work only thanksNote:- Study this program and follow the given instruction and type execute the code and also give output for this java program as soon as possible. Modify example six to read file tooutfile2.txt compute and display the total. Then write the total to a file named tooutfile2A.txt exampleSix This program creates file tooutfile2.txt and stores 10 integers in it Please verify that the file was created along with the content package pwriter2; import java.util.Scanner; import java.io.*; public class Pwriter2 { public static void main(String[] args) throws IOException { PrintWriter tofile2 = new PrintWriter( "tooutfile2.txt" ); int i = 0; while (i < 10){ tofile2.println( i ); i = i + 1; } tofile2.close(); } }please use python language instruction- 1. Read the code from line 123 to line 137. This is the basically the selection. Remember how we talk about there are certain things about controlling population? Please explain how we make sure that the population, when going through a selection, does not shrink over generation. You may simply explain this as comments in a Python file as opposed to in a Word file:. Note that the code from line 123 to line 137 is divided into two small blocks. Use that as 2. The code we've just examined has one functionality of selection. So, we really should wrap that into one function nanied 'select'. Note that in this file there is no class named 'Population'. So, you should make this function a static method that belongs to the class named 'Individual', or a simple function that resides outside the class named 'Individual'. Please think about what the inputs and output of this function are before you start coding. Once you have created the…
