Dr. Sturm HW #8 – class Ratio

//class Ratio

//Write methods operator+, operator-, operator/, and reduce.

//Test each one separately.

//Hand in the completed class Ratio together with the main function that tests each method

#include <string.h>

#include <iostream.h>

#include <conio.h>

class Ratio{

private:

int num;

int den;

public:

Ratio(int n=0,int d=1);

void setRatio(int n,int d);

void reduce();

Ratio invert();

Ratio operator+(Ratio op2);

Ratio operator-(Ratio op2);

Ratio operator*(Ratio op2);

Ratio operator/(Ratio op2);

void display();

};

num=n;

}

void Ratio::setRatio(int n,int d){

}

void Ratio::reduce(){

//This method reduces the Ratio

//For example, if r1=4/6, then after

// r1.reduce(), Ratio r1 will be equal

//to 2/3.

}//end reduce

void Ratio::display(){

if(den!=1)

cout<<num<<"/"<<den<<endl;

result.num=num*op2.num;
