Question

What are the two default operators the compiler generates a default implementation for?

a) + and -
b) * and /
c) = and !=
d) == and !=

Answer 1

The compiler generates default implementations for the equality (==) and inequality (!=) operators for classes and structs in languages like C++.

Step-by-step explanation:

The two default operators the compiler generates a default implementation for are == and !=. These operators represent the equality and inequality checks, which are fundamental to the operation of a class or struct in many programming languages, especially in C++. When you create a class or struct, the compiler will automatically generate a default implementation for these operators if you do not provide one, allowing objects of that class or struct to be compared for equality or inequality.

However, it's often necessary to provide a custom implementation of these operators to ensure they behave correctly for the specific attributes of your objects.
