#ifndef PROCESSREQUESTRECORD_CLASS

#define PROCESSREQUESTRECORD_CLASS

#include <iostream>

#include <string>

using namespace std;

class procReqRec

{

public:

// default constructor

procReqRec()

{}

// constructor

procReqRec(const string& nm, int p);

// access functions

int getPriority();

string getName();

// update functions

void setPriority(int p);

void setName(const string& nm);

// for maintenance of a minimum priority queue

friend bool operator< (const procReqRec& left,

const procReqRec& right);

// output a process request record in the format

// name: priority

friend ostream& operator<< (ostream& ostr,

const procReqRec& obj);

private:

string name; // process name

int priority; // process priority

};

#endif // PROCESSREQUESTRECORD_CLASS

procReqRec.cpp

#include"procReqRec.h"

// constructor

procReqRec::procReqRec(const string& nm, int p)

{

name=nm;

priority=p;

}

// access functions

int procReqRec:: getPriority()

{

return priority;

}

string procReqRec:: getName()

{

return name;

}

// update functions

void procReqRec::setPriority(int p)

{

priority=p;

}

void procReqRec::setName(const string& nm)

{

name=nm;

}

ostream& operator<< (ostream& ostr,const procReqRec& obj)

{

return ostr<<obj.name<<":"<<obj.priority;

}

bool operator < (const procReqRec& left,const procReqRec& right)

{

return left.priority< right.priority;

}

main.cpp for testing

#include"procReqRec.h"

using namespace std;

int main()

{

procReqRec p1("process1",5);

procReqRec p2("process2",10);

cout<<p1<<endl;

cout<<p2<<endl;

if(p1<p2)

cout<<"\n\nPriority of p1 is less then priority of p2"<<endl;

else

cout<<"\n\nPriority of p1 is greater then priority of p2"<<endl;

return 0;

}

output
