Question

C++C++

Exercise 1: Create a class Resource. The class should have: a) Two private variables status and writeTo representing integer value either 0 or 1. b) One default constructor that initializes the status and writeTo to zero. c) One single parameterized constructor to initialize the writeTo variable. d) Two constant accessor functions per class that return the values of status e) Two mutator functions per class that set the values of status and writeTo One output (member) function that outputs the resource status. The output and writeTo separately separately. function should be able to print on the screen or an output file. void output (ostream sout_stream) g) A friend function check status that accesses the status variables of two input objects. If status in each resource object is set to "1", display "resource available" else display "resource unavailable bool check status (Resource sresl, Resource sres2) // Define status checking code here return crue if r /1 else return false status and res2 status are both 1

Answer 1

#include <iostream>
using namespace std;

class Resource
{
private:
int status,writeTo;

public:
Resource()
{
status = 0;
writeTo = 0;
}
Resource(int writeTo)
{
this->writeTo = writeTo;
}
int getStatus()const
{
return status;
}
int getWriteTo()const
{
return writeTo;
}

void setStatus(int status)
{
this->status = status;
}
void setWriteTo(int writeTo)
{
this->writeTo = writeTo;
}
void output(ostream &out_stream)
{
out_stream<<"Status : "<<status<<" Write To : "<<writeTo;
}

friend bool check_status(Resource &res1, Resource &res2);
};

bool check_status(Resource &res1, Resource &res2)
{
// Define status checking code here.
// return true if res1 status and res2 status are both 1
if(res1.status == 1 && res2.status == 1)
return true;
// else return false.
else return false;
}

int main() {
Resource r1(0);
Resource r2(1);

r1.output(cout); // cout is used to display on screen

if(check_status(r1,r2))
cout<<"\nStatus of resource r1 and r2 are same ";
else
cout<<"\nStatus of resource r1 and r2 are not same ";
return 0;
}

output:

Status : 0 Write To : 0
Status of resource r1 and r2 are not same
