Overload assignment operator

# include
class sample
{< br> int N;
Public:
sample () {}< br> sample (int I) {n = I ;}< br> sample & operator = (sample S) // overload assignment operator
{< br> N = s. n;
return * This;
}< br> void disp ()
{< br> cout <"n =" }< BR >};
void main ()
{< br> sample S1 (10), S2;
S2 = S1;
cout <<"S1: "; s1.disp ();
cout <" S2: "; s2.disp ();
}

description: "operator = member function" is used to assign values to two objects. However, if you remove the member functions of the overload operator, the Program can still run. Normally, the system automatically generates a default value assignment operator for each class to complete the assignment operation between objects.
