Complete the following. • Write the definition of a function template that swaps the contents of two variables along with a test program demonstrating that it works with different types. • Hints: • Remember, a template definition must start with template , where T is simply a variable name and will serve as a place holder for the data type being passed into the template. • When defining a template the code defining the function goes inside the header file, so you'll only have two files: SwapTemplate.h and TestProgram.cpp (Or some similar file names.) • Don't overthink this. There's not much code at all in the solution. Submit: Commented source for swap template and test zipped into a single file.

Write templates for the two functions min and max. min should accept two arguments and return the value of the argument that is the lesser of the two. max should accept two arguments and return the value of the argument that is the greater of the two. Design a simple driver program that demonstrates the templates with various data types.
In C++ I need to write templates for the two functions minimum and maximum. The minimum function should accept three arguments and return the value of the argument that is the lesser of the three. The maximum function should accept three arguments and return the value of the argument that is the greater of the three. Design a simple driver program that demonstrates the templates with int, float, and double data types.
Moving Between Rooms - Navigation In this assignment, you will be working with a given "rooms" dictionary and associated constants to create a simple text-based game. Your main task is to develop a function that allows the player to navigate through the rooms based on the given specifications. You need to implement the function found in the starter code to the right The function should take into account the following conditions: If the direction leads to an exit, set the next room to the exit and the message to "Goodbye". If the direction is invalid, set the next room to the current room and the message to "No such direction". If the direction is valid, but you cannot go that way, set the next room to the current room and the message to "You bumped into a wall". If the direction is valid and you can go that way, set the next room to the room in that direction and the message to "Empty". To help you understand how the function will be integrated into the gameplay loop, the following…
There should be a file for each. One file for EACH class(2 files), their function files (2 files) and a main file(1 file). In total, 5 files and its a class not a struct.
4. Absolute Value Template Write a function template that accepts an argument and returns its absolute value. The absolute value of a number is its value with no sign. For example, the absolute value of -5 is 5, and the absolute value of 2 is 2. Test the template in a simple driver program being sure to send the template short, int, double, float, and long data values. SAMPLE RUN #4: ./AbsoluteValueTemplate Hide Invisibles Highlight: None Show Highlighted Only O Interactive Session Enter.a short.or.just.enter to-move.to.next.data type:-124 The absolute. value of.-12.is: 124 Enter.a short.or.just.enter to-move to. next data type:-11- The absolute value of.-11·is: 11e Enter.a short.or.just.enter to-move.to.next.data -type:-84 The absolute value of. -8.is: 84 Enter.a short.or.just.enter to-move to-next.data type:88e The absolute value of. 88 -is: 88e Enter.a short.or.just.enter to-move.to.next data type:45e The absolute value of.45.is: 45- Enter.a short.or.just.enter to-move -to-next.data…
Language: C++ Use the previously given files: Critter.h, Critter.cpp and testcritter.cpp. Expand Critter.h by two additional properties of your choice, and corresponding setter and getter methods, then adjust Critter.cpp and testcritter.cpp accordingly. Also adapt the print () method such that the new properties are printed on the screen as well. You can assume that the input will be valid.
Problem description: Write a python application to simulate an Amazon online book shoppingsystem, namely “Amazing”. Design solution: The template file contains a list of books sold on Amazing, each item in the listcontains the title, publication year, author and the prices. The program will generate anitems_dict where each key is the title of the book and the values will be a list of year, authorand price information. A customer will be presented with a main menu with 4 different options:display all items, add an item to cart, checkout and exit the program. A customer can buy anitem by entering the title of the book. This program implements a dictionary called cart, whereeach key is the title and the values are the list of year, author and price and We assume onecopy is added with each selection. The program keeps repeating by displaying the main menuto user until user hits the quit button. If user hits the checkout option, the program will displayall the items in the cart and display…
Topical Information Use C++. The purpose of this project is to test your ability to use files, class design, operator overloading, and Strings or strings effectively in program design. Program Information Create a program which will read a phrase from the user and create a framed version of it for printing. For example, the phrase "hello world"would result in: ********* * hello * * world * ********* Whereas the phrase "the sky is falling"might be: *********** * the * * sky * * is * * falling * *********** Or: *********** * the * * sky * * is * * falling * *********** Or even: *********** * the * * sky * * is * * falling * *********** Depending on whether or not the user asked for left, centered, or right justification — respectively — of the phrase's words within the frame. Note how the frame exactly fits the phrase based on the longest word within. Neat, eh? The phrase "O | -+- | /-\"when centered would become:…
Language : C++ Subject : OOP Suppose we have a class Rectangle which has two data members, length and width. In addition, there should be a static variable, namely allRectanglesTotalArea which stores the area of all the Rectangles created. Furthermore, there should be a function named calcRectangleArea() which calculates the area of rectangle and adds it to the allRectanglesTotalArea. Write a static function nameddisplayAllRectanglesTotalArea()which displays the value of allRectanglesTotalArea. The main function of the program should look like the following. intmain() { Rectangle r1(5.0,4.0); r1.calcRectangleArea(); Rectangle r2(2.5,4.0); r2.calcRectangleArea(); Rectangle::displayAllRectanglesTotalArea(); return 0; }
Topical Information Use C++. This lab is designed to give you practice with labeled data in files. Again, classes can help ease your design woes. Program Information Write a program that transfers the contents of one file to a second file. The first file will contain an arbitrary (unknown) number of data groups. A data group will normally consist of a person's name (a string containing spaces), the person's student ID (a large integer), the person's GPA (a floating point number), and the person's gender (a character). The data in each group should be in a labeled data format. Be sure to use some kind of string library to help you with the label/value processing (as we discussed in class). (The library provided here is good but not everything you'll need. You still need functions to convert strings into integers and into floating point numbers. string to bool, string to string, and string to character conversions should be fairly easy.) You can choose the actual values to use for the…
What must you be sure of when passing a class object to a function template that uses an operator, such as * or >?
In the source file (CPP), create a C++ class that contains your functions and data members as follows: • Data members: · 2 arrays of strings named names and values respectfully (do not use STL containers e or your score will be reduced significantly). The size of the arrays should be large enough to hold all of the data parsed from the test files (we will be modifying this in the future so don't worry about the size being just right. Err on the side of too large if anything). • names array: will contain all of the names in the object • values array: will contain all of the values in the object Member functions: · A function to open the file and store the file object or data. The function should return true on success and false on failure. · A function to read the names/values from the JSON file and place them in the 2 member arrays named names and values respectfully. The function should return true on success and false on failure. • Create docktest e testcases that tests the results…
