Answer to Question #316453 in C++ for Rin

Question

Problem:

Create a Fraction class with two private positive integer member variables numerator and denominator, one

constructor with two integer parameters num and den with default values 0 and 1, one display function that

print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4

should be displayed as ½.

Answer 1

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;


class Fraction {
private:
	int numerator;
	int denominator;
		int gcd(int m, int n) {
		if (0 == n)
			return m;
		else
			return gcd(n, m % n);
	}
public:
	
	Fraction(int numerator, int denominator) {
		if (denominator == 0) {
			cout<<"Denominator is zero.\n\n";
		}
		int g = gcd(numerator, denominator);
		this->numerator = numerator / g;
		this->denominator = denominator / g;


	}
	
	void print(){


		if (denominator == 1){
				cout<<numerator;
		}
		else{
			cout<<numerator << "/" << denominator;
		}
	}




	~Fraction(){


	}




};




int main(void){


	Fraction f1(4,8);
	f1.print();
	cout<<"\n\n";
	Fraction f2(3,8);
	f2.print();


	cout<<"\n\n";
	
	system("pause");
	return 0;
}
