Question

please do this in C++! I want to understand it, it must be done before the evening or nightime. Follow instructions exactly as it says. Please send a screenshot also with your code so I can see how it is supposed to be formatted. Since typing it a chegg answer, makes it look a bit messy.

Your program will read in a file of commands. There are three types of commands:

Warrior creates a new warrior with the specified name and strength. Battle causes a battle to occur between two warriors. Status lists all warriors, alive or dead, and their strengths.

A sample input file looks like:

“Warrior Jim 42

Warrior Lancelot 15

Warrior Arthur 15

Warrior Torvalds 20

Warrior Gates 8

Status

Battle Arthur Lancelot

Battle Jim Lancelot

Battle Torvalds Gates

Battle Gates Lancelot

Status”

The name of the input file will be "warriors.txt". Note that the commands do not have to appear in that order. The only requirement is that a Battle command cannot appear until the specified warriors have been seen.

The Status command displays how many warriors there, then displays each one with his strength. The Warrior command does not display anything. The Battle command displays one line to says who is fighting whom and a second line to report the results, as shown below.

The output (which would display on the screen) for this file should look like:

“There are: 5 warriors

Warrior: Jim, strength: 42

Warrior: Lancelot, strength: 15

Warrior: Arthur, strength: 15

Warrior: Torvalds, strength: 20

Warrior: Gates, strength: 8

Arthur battles Lancelot

Mutual Annihilation: Arthur and Lancelot die at each other's hands

Jim battles Lancelot

He's dead, Jim

Torvalds battles Gates

Torvalds defeats Gates

Gates battles Lancelot

Oh, NO! They're both dead! Yuck!

There are: 5 warriors

Warrior: Jim, strength: 42

Warrior: Lancelot, strength: 0

Warrior: Arthur, strength: 0

Warrior: Torvalds, strength: 12

Warrior: Gates, strength: 0”

For the sequence of commands, your output should looke exactly as shown above. Please don't exercise you creativity here.

Use a struct. That means we do not want you to define classes or methods, or to use data hiding.

Make good use of functions. In this program, for example, when you determine that you are looking at a Warrior command then you should call a function to handle that command. Similarly with the other commands. The program should have a "reasonable" amount of useful comments explaining what each part of your code does. The code must be well formatted. Never turn in code with bad indentation.

All structs, functions and variables should have good names. Function names should clearly identify what the function does. Follow the convention that structs begin with an uppercase letter, constants are all uppercase and functions and variables begin with a lowercase letter.
