Put the code you need help with here.
#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;
//#include "CFraction.h"
class CFraction
{
private:
int m_nN ;
int m_nD ;
public:
CFraction();
void setNumerator(int nN);
bool setDenomirator(int nD);
bool isInteger();
bool isProper();
void print();
};
CFraction::CFraction()
{
m_nN = 0;
m_nD = 1;
}
// setNumerator-Methode(Funktion)
void CFraction::setNumerator(int nN)
{
//cin>>nN;
m_nN=nN;
}
// setDenomerator-Methode(Funktion)
bool CFraction::setDenomirator(int nD)
{
if (nD!=0)
{
m_nD=nD;
return true;
}
else
{
return false;
}
}
//isInteger-Methode(Funktion)
bool CFraction::isInteger()
{
float Bruch=m_nN%m_nD;
if(Bruch==0)
{ cout<<m_nN<<"/"<<m_nD<<" ";
cout<<"ganzzahlig ";
return true;
}
else
{ cout<<m_nN<<"/"<<m_nD<<" ";
cout<<"nicht ganzzahlig ";
return false;
}
}
//isProper-Methode(Funktion)
bool CFraction::isProper()
{
int n ,m;
n=abs(m_nN);
m=abs(m_nD);
if(n<m)
{
cout<<"echt"<<endl;
return true;
}
else
{
cout<<"nicht echt"<<endl;
return false;
}
}
void CFraction::print()
{
//cout<<endl<<"Zähler ="<<m_nN<<endl;
//cout<<"Nenner ="<<m_nD;
}
int main (void)
{
cout << "ubung2 gestarted." << endl << endl;
CFraction f,Bruch; // Deklaration ein Bruch und f-Objekt
// Methoden(Funktionen) aufrufen
CFraction();
Bruch.setNumerator(4);
Bruch.setDenomirator(3);
//Bruch.isInteger();
//Bruch.isProper();
Bruch.print();
return 0;
}

Like so:

void CFraction::print()
{
if(isInteger())
do_something;
if(isProper())
do_something_else;
}
|
it works .
thank you coder777 :)
