Umeed Hai Aap Sab Khairiyat Sy Hon gy...

ye mera pehla thread hai... Umeed karta hoon aap logo sy acha feedback mily ga..

ye program mny qareeban 1 saal pehly fraction addition k liye banaya tha umeed karta hoon aap logo ko pasnd aye ga



Code:

#include<iostream>
#include<conio.h>
using namespace std;


class Fa
{
protected:
	int n1,d1;
	char op;
public:
	Fa()
	{
		n1=0;d1=0;
	}
	void input()
	{
		cout<<"\nEnter Fraction in this format (Numerator / Denuminator): ";
		x:cin>>n1>>op>>d1;
		if(!(op=='/'))
		{
			cout<<"\nInvalid Entry. Enter Correct Operator i.e /: ";
			goto x;
		}
	}
	void dis()
	{
		cout<<"\nResult is : "<<n1<<op<<d1;
		cout<<"\nPress Any Key to Continue...";
	}

};

class Fb:public Fa
{
	int n2,n,d,d2,cn1,cn2;
	char op;
public:
	Fb()
	{
		n2=0;d2=0;n=0;d=0;
	}
	void input()
	{
		cout<<"Enter two fractions to add:"<<endl;
		Fa::input();
		cout<<"\nEnter another Fraction in this format (Numerator / Denuminator): ";
		y:cin>>n2>>op>>d2;
		if(!(op=='/'))
		{
			cout<<"\nInvalid Entry. Enter Correct Operator i.e /";
			goto y;
		}
	}
	void add()
	{
		if(d1==d2)
			d=d1;
		else if(d1%d2==0)

			}
		}
		cn1=(d/d1)*n1;

	}
	void dis()
	{
		cout<<endl<<n1<<op<<d1<<" + "<<n2<<op<<d2<<" = "<<n<<op<<d<<endl;
	}
};


void main()
{
	char op;
	Fb ob;
	do
	{
		system("cls");
		ob.input();
		ob.add();
		ob.dis();
		cout<<"\nWant to Add Again (Y/N): ";
		a:op=getche();
		if(!(op=='y'||op=='Y'||op=='N'||op=='n'))
		{
			cout<<"\nInvalid Selection at Y/N. Enter Again:";
			goto a;
		}
	}
