Two similar Operators in C | Part-1 | Types of Operators in Tamil | Unary, Binary, Ternary Operator with ExampleIn this video we will discuss about what is operator and Unary operators in C and C++: Explain unary operators with explanation and examples in C and C++ programming language, this tutorial contains detailed explanation about unary operators like unary plus, minus, increment, decrement, address of, sizeof, dereferencing, logical NOT, bitwise NOT with examples. In a case, where the value of the operator is NULL , the typeof returned by the unary operator is___. a) undefined b) string c) boolean d) object The unary operators operate on the object for which they were called and normally, this operator appears on the left side of the object, as in !obj, -obj, and ++obj but sometime they can be used as postfix as well like obj++ or obj--.
