Slip 15 - A) Create a C++ class Fraction with data members Numerator and Denominator. Write a C++ program to calculate and display sum of two fractions. (Use Constructor).

 Solution:

#include<iostream>

#include<conio.h>

using namespace std;

class fraction

{

int num,dnm;

public:

fraction(){}

fraction(int n,int d)

{

num=n;

dnm=d;

}

void operator +(fraction);

};

void fraction::operator + (fraction f2)

{

cout<<"\n Addition : ";

num=num*f2.dnm+f2.num*dnm;

dnm=dnm*f2.dnm;

cout<<num<<"\\"<<dnm;

}

int main()

{

int n1,d1,d2,n2;

cout<<"Enter first fraction :"<<endl;

cin>>n1>>d1;

cout<<"Enter second fraction :"<<endl;

cin>>n2>>d2;

fraction f1(n1,d1);

fraction f2(n2,d2);

fraction f3;

f1+f2;

return 0;

}
