c++ please The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include using namespace std; #include "critter.h" /** A sloth eats and sleeps. */ class Sloth : public Critter { public: Sloth(); . . . private: . . . }; Sloth::Sloth() { . . . } void Sloth::act() { if (...) { add_history("eat"); ... } else { add_history("sleep"); ... } } int main() { Sloth sloth; sloth.act(); cout << sloth.get_history() << endl; cout << "Expected: [eat]" << endl; sloth.act(); cout << sloth.get_history() << endl; cout << "Expected: [eat, sleep]" << endl; sloth.act(); cout << sloth.get_history() << endl; cout << "Expected: [eat, sleep, eat]" << endl; sloth.act(); cout << sloth.get_history() << endl; cout << "Expected: [eat, sleep, eat, sleep]" << endl; return 0; } Use the following file: critter.h #ifndef CRITTER_H #define CRITTER_H #include #include using namespace std; /** A simulated critter. */ class Critter { public: /** Constructs a critter at position 0 with blank history. */ Critter(); /** Gets the history of this critter. @return the history */ string get_history() const; /** Adds to the history of this critter. @param event the event to add to the history */ void add_history(string event); /** Gets the position of this critter. @return the position */ int get_position() const; /** Moves this critter. @param steps the number of steps by which to move. */ void move(int steps); /** The action of this critter in one step of the simulation. */ void act(); private: int position; vector history; }; #endif

The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter.
Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called.
The implementation of the Critter class is not shown.
Complete the following file:
sloth_Tester.cpp
#include <iostream>
using namespace std;
#include "critter.h"
/**
A sloth eats and sleeps.
*/
class Sloth : public Critter
{
public:
Sloth();
. . .
private:
. . .
};
Sloth::Sloth()
{
. . .
}
void Sloth::act()
{
if (...)
{
add_history("eat");
...
}
else
{
add_history("sleep");
...
}
}
int main()
{
Sloth sloth;
sloth.act();
cout << sloth.get_history() << endl;
cout << "Expected: [eat]" << endl;
sloth.act();
cout << sloth.get_history() << endl;
cout << "Expected: [eat, sleep]" << endl;
sloth.act();
cout << sloth.get_history() << endl;
cout << "Expected: [eat, sleep, eat]" << endl;
sloth.act();
cout << sloth.get_history() << endl;
cout << "Expected: [eat, sleep, eat, sleep]" << endl;
return 0;
}
Use the following file:
critter.h
#ifndef CRITTER_H #define CRITTER_H #include <string> #include <vector> using namespace std; /** A simulated critter. */ class Critter { public: /** Constructs a critter at position 0 with blank history. */ Critter(); /** Gets the history of this critter. @return the history */ string get_history() const; /** Adds to the history of this critter. @param event the event to add to the history */ void add_history(string event); /** Gets the position of this critter. @return the position */ int get_position() const; /** Moves this critter. @param steps the number of steps by which to move. */ void move(int steps); /** The action of this critter in one step of the simulation. */ void act(); private: int position; vector<string> history; }; #endif
