You can overload the assignment operator (=) just as you can other operators and it can be used to create an object just like the copy constructor. Following example explains how an assignment operator can be overloaded.
Which operators in C can be overloaded?
Most can be overloaded. The only C operators that can’t be are . and
?: (and sizeof , which is technically an operator)
. C++ adds a few of its own operators, most of which can be overloaded except :: and .
Does C allow operator overloading?
No, C doesn’t support any form of overloading
(unless you count the fact that the built-in operators are overloaded already, to be a form of overloading). printf works using a feature called varargs

Is ++ an assignment operator?
Assignment Operators in C/C++ Assignment operators are
used to assigning value to a variable
. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value.
Is printf overloaded in C?
4 Answers. printf() in C is a variadic function
Which operators Cannot be overloaded?
- ?: (conditional)
- . ( member selection)
- .* (member selection with pointer-to-member)
- :: (scope resolution)
- sizeof (object size information)
- typeid (object type information)
- static_cast (casting operator)
- const_cast (casting operator)
Can == be overloaded?
You cannot use it for built-in types (float, char, int, etc.).
The = and & C++ operators are overloaded by default
. For example, you can copy the objects of the same Class directly using the = operator. Operator precedence doesn’t change the associatively and precedence of operators.
Can we overload operator?
You can only overload existing operators
. You can’t overload new operators. Some operators cannot be overloaded using a friend function. However, such operators can be overloaded using member function.
How many assignment operators are there?
There are
two kinds of assignment
operations: simple assignment, in which the value of the second operand is stored in the object specified by the first operand. compound assignment, in which an arithmetic, shift, or bitwise operation is performed before storing the result.
What does the assignment operator do?
The assignment operators
return the value of the object specified by the left operand after the assignment
. The resultant type is the type of the left operand. The result of an assignment expression is always an l-value. These operators have right-to-left associativity.
What is overriding in C?
Function overriding helps us achieve
runtime polymorphism
. It enables programmers to perform the specific implementation of a function already used in the base class.
Why overloading is not possible in C?
Function Overloading allows us to have multiple functions with the same name but with different function signatures in our code. These functions have the same name but they work on different types of arguments and return different types of data. … Therefore,
C does not support function overloading
.
What is the size of double pointer in C?
The size of a double pointer is
8 bytes
