Write a c++ program to implement the overloading assignment = operator


AIM: Write a C++ program to illustrate assignment operator overloading.


An assignment operator is the operator used to assign a new value to a variable, property, event or indexer element in C# programming language. Assignment operators can also be used for logical operations such as bitwise logical operations or operations on integral operands and Boolean operands.
Unlike in C++, assignment operators in C# cannot be overloaded directly, but the user-defined types can overload the operators like +, -, /, etc. This allows the assignment operator to be used with those type
The following are the characteristics of assignment operators:

  • When using the “=” operator for an assignment with the left operand as the property or indexer access, the property or indexer must have a set accessor.
  • Overloading a binary operator implicitly overloads its corresponding assignment operator (if any).
  • The different assignment operators are based on the type of operation performed between two operands such as addition (+=), subtraction, (-=), etc. The meaning of the operator symbol used depends on the type of the operands.
  • Assignment operators are right-associative, which means they are grouped from right to left
  • nment using assignment operator (a += b) achieves the same result as that without ( =a +b), the difference between the two ways is that unlike in the latter example, “a” is evaluated only once.
  • The assignment operator usually returns a reference


using namespace std;
class A
    int a,b;
    A(){  a=b=0;   }
    A (int m,int n)
    void operator=(A ob)
    void show()
        cout<<“a= “<<a<<“\t b= “<<b<<endl;
int main()
    int a,b;
    cout<<“Enter two values:\n”;
    A ob1(a,b),ob2;
    cout<<“Values of first object are:\n”;
    cout<<“Values of second object before assign:\n”;
    cout<<“Values of second object after assign:\n”;


Enter two values:
85           63
Values of first object are:
a=85      b=63
Values of second object before assign:
a=0         b=0
Values of second object after assign:
a=85      b=63
