const Primitive Data Type
Understand the use of const with primitive data types in C++ function parameters. Learn why passing fundamental types by value is preferred over const references and how const improves code safety without compromising efficiency.

Let’s explore when to use const parameters in the parameter list of function signatures. Let’s differentiate between fundamental types (also known as primitive data types) and class types.
Introduction
This section talks about primitive data types, such as bool, int, float, char, etc.
Should such parameters be taken as const?
The answer is no, because it will be inefficient. We can access these data types with one memory read if ...
