The document discusses operator overloading in C++. It defines a unary class with integer data members x, y, and z. It overloads the unary minus operator to change the sign of x, y, and z. The main function creates a unary object, displays its member values, applies the unary minus operator, and displays the values again to show the signs have changed.

2. OPERATOR OVERLOADING
#include<iostream.h>
#include<conio.h>
class unary
{
Int x,y,z;
public;
unary(int a,int b,int c)
{
x=a;
y=b;
z=c;
}

3. void disp()
{
cout<<“nx=“<<x<<“ny=“<<y<<“nz=“<<z;
}
void operator-();
};
void unary::operator-()
{
x=-x;
y=-y;
z=-y;
}
Int main()

4. int main()
{
unary ob(56,-67,56);
clrscr();
Ob.disp();
-ob;
cout<<“nAfter the minus operator the values are:”;
ob.disp();
getch();
Return0;
}

5. OUTPUT:
x=56
y=-67
z=-56
After the minus operator the values are
x=-56
y=67
z=56
