Program for Operator Overloading.
1.
Unary Operator
Overloading:
Code:
#include<iostream>
using
namespace std;
class
INC
{
int a , b, c;
public:
INC(int a1 , int b1, int c1)
{
a=a1;
b=b1;
c=c1;
}
void operator ++ ()
{
++a;
++b;
++c;
}
void show()
{
cout<<"\nValues after
Increment : ";
cout<<"\na="<<a<<"\nb="<<b<<"\nc="<<c;
}
};
int
main()
{
INC A(1,2,3) , B(11,22,33);
++A;
A.show();
++B;
B.show();
}
2.
Binary Operator
Overloading :
Code:
#include<iostream>
using
namespace std;
class Binary
{
int a;
public:
Binary(int a1)
{
a=a1;
;
}
int operator + ( Binary b1 )
{
int c;
c=a+b1.a;
return c;
}
int operator - ( Binary b1)
{
int c;
c=a-b1.a;
return c;
}
int operator * ( Binary b1)
{
int c;
c=a*b1.a;
return c;
}
int operator / ( Binary b1)
{
int c;
c=a/b1.a;
return c;
}
void show()
{
cout<<"\nValues Entered :
";
cout<<"\na="<<a;
}
};
int
main()
{
Binary B(2) , A(11);
int C;
A.show();
B.show();
cout<<"\n";
C=A+B;
cout<<"\nValue after changes
:"<<C;
C=A-B;
cout<<"\nValue after changes
:"<<C;
C=A*B;
cout<<"\nValue after changes
:"<<C;
C=A/B;
cout<<"\nValue after changes
:"<<C;
}
