sizeof operator in C++ is an unary operator which can be used to find the size of the data-type or expression or a variable. It returns the size of the memory allocated (in Bytes) by the compiler. Lets say, we want to find the size of the memory allocated to the data-type int. We can find it by using sizeof operator as shown in the below code:

Output:

As you can see, the above code calculated the size of int data type and displayed the result in C++.
