Virtual base class C++ Program TO find perfect numbers within range

By: Prof. Fazal Rehman Shamil

Write a C++ program to find the perfect numbers within a given number of range by using the virtual base class in Object Oriented Programming.

#include<iostream>
using namespace std;
class A
{
protected:
int num,T4Tutorials_SUM;
};
class B:public virtual A
{
protected:
int st,end;
B()
{
st=10;
end=50;
}	
};
class C:public virtual A
{
public:
int i;
};
class D:public B, public C
{
public:
void show()
{
for(num=st;num<=end;num++)
{
i=1;
T4Tutorials_SUM=0;
while(i<num)
{
if(num%i==0)
T4Tutorials_SUM=T4Tutorials_SUM+i;
i++;
}
if(T4Tutorials_SUM==num)
cout<<"The perfect number within the given range are given below."<<endl<<num<<endl;
}	
} 
};	
int main()
{
D object_t4tutorials;
//	obj.in();
object_t4tutorials.show();
}

#include<iostream>

using namespace std;

class A

{

protected:

int num,T4Tutorials_SUM;

};

class B:public virtual A

{

protected:

int st,end;

B()

{

st=10;

end=50;

}

};

class C:public virtual A

{

public:

int i;

};

class D:public B, public C

{

public:

void show()

{

for(num=st;num<=end;num++)

{

i=1;

T4Tutorials_SUM=0;

while(i<num)

{

if(num%i==0)

T4Tutorials_SUM=T4Tutorials_SUM+i;

i++;

}

if(T4Tutorials_SUM==num)

cout<<"The perfect number within the given range are given below."<<endl<<num<<endl;

}

};

int main()

{

D object_t4tutorials;

// obj.in();

object_t4tutorials.show();

}

Output

The perfect number within the given range are given below.
