Create a new file (in Dev C++) and save it as lab11_XYZ.cpp (replace XYZ with your initials). Create ANOTHER new file (in Dev C++) and save it as swap_XYZ.h (replace XYZ with your initials). Use the swap_XYZ.h header file to define a set of functions for swapping two items of the same type. Given the following prototypes, define (overloaded) swap functions void swap(int&, int&); //swap two integers void swap(double&, double&); //swap two doubles void swap(float&, float&); //swap two floats void swap(char&, char&); //swap two characters void swap(string&, string&); //swap two strings The header file should contain the following: header comments (similar to normal program header comments) function definitions (for you to do, based on provided prototypes above...) In general, a swap works like this: void swap(type first&, type second&){ type temp = first; first = second; second = temp; } Once your header file is complete, make…

Please use python not java or C++ A straight line can be defined by a pair of points p1(x1, y1) and p2(x2, y2). The slope m of a line is defined as follow: ? = ?% − ?' ?% − ?' Your program reads the points from a text file called ‘points.txt’ which contains the coordinates of unknown number of pairs of points as shown in Figure 1. Each line contains four values x1, y1, x2, y2, where x1, y1 are the coordinates of the first point and x2, y2 are the coordinates of the second point. Figure 1. Input file contains unknown number of point pairs Use Spider, to create the following files: (i) The input file ‘points.txt’ shown in Figure 1. (ii) Your Python program that reads from the input file ‘points.txt’, the coordinates of unknown number of pairs of points, computes the corresponding slopes then prints the results on the screen as shown in Figure 2.

2.a. Write a class with name EmployeeInfo that will keep track of employees name,salary, post, and joining year. Create a text file with information of five employeesof a company. Each row in the file should contain four columns. Read this filewith python and using the EmployeeInfo class, find out the employee with highestsalary and also find out the employee with longer time with company.b. Using the EmployeeInfo class and the same file, sort the employees in ascendingorder of salary using list’s functions.
USE PYTHON Before there were emoji, there were emoticonsLinks to an external site., whereby text like :) was a happy face and text like :( was a sad face. Nowadays, programs tend to convert emoticons to emoji automatically! In a file called faces.py, implement a function called convert that accepts a str as input and returns that same input with any :) converted to ? (otherwise known as a slightly smiling faceLinks to an external site.) and any :( converted to ? (otherwise known as a slightly frowning faceLinks to an external site.). All other text should be returned unchanged. Then, in that same file, implement a function called main that prompts the user for input, calls convert on that input, and prints the result. You’re welcome, but not required, to prompt the user explicitly, as by passing a str of your own as an argument to input. Be sure to call main at the bottom of your file. ( Please see attached file for Demo) use PYTHON
Modify the program 11-10 from pages 753-755 as follows: 1. To Length class files (Length.h and Length.cpp) add the operator overload for stream insertion (<<) and stream extraction (>>) from page 759. You should not use the modified version of class Length from page 759 because it contains more operator overloads. Instead of typing you can use copy/paste from Length1.h and Length1.cpp respectively. 2. In main() replace the lines 11-16 with appropriate usage of stream extraction overload (>>) to change "first" and "second" objects with values inputted by the end user. 3. In main(), replace the output on lines 21,22 and 25,26 with appropriate usage of stream insertion (<<) operator. The resulting output should be identical with the unmodified version of the program. 11-10: // This program demonstrates the Length class's overloaded // +, -, ==, and < operators. #include <iostream> #include "Length.h" using namespace std; int main() { Length first(0),…
(a) In Java: we use class ……………………. to input text from a file. (b) Files created using byte-based streams are……… , while files created using character-based streams are………… {Fill in the 2 blanks from these: text files , binary files}. (c) Write Java code to print 2-dimensional array arr1 and 2-dimensional array arrx in two different ways. (d) Given a generic class called MyFirstGenericC: In two lines of code: instantiate two objects of this class.
1. Given two .txt files that have lists of numbers in them, find the numbers that areoverlapping (print them in the output). “primenumbers.txt” has a list of all primenumbers under 1000, and the other “happynumbers.txt” has a list of happy numbersup to 1000.We can divide this problem into different parts:a. Write a function (call it readFile) that takes the name of a file as argument and read the content of the file and store it in a list (each line contains onenumber, so each number is stored in the list) and return the list.b. Write a function that takes two lists and return another list containing thecommon elements of two lists (you have written this function before! You canuse it)c. Write a function (call it writeFile) that takes a list and name of a file. The function should write the content of the list in the file (each element in oneline).d. Use the above functions to do the task of this lab.
