static function c vs c++

Should I use static function in C?
Unlike global functions in C, Static functions are only accessible from the file where they are declared.
As a result, we make functions static when we want to limit access to them.
Another reason to make functions static is to avoid reusing the same function name across many files.
By avoiding instance data access, static methods can be more efficient and faster than instance methods.
This is because they do not need to access instance-specific data, and can be optimized for performance.

What happens when you declare a function static C?

Short Answer: It means the function name is only visible and callable in the file being compiled currently.
Other files compiled separately will not see the function name or be able to call it.
Subsequently, they may have their own static functions of the same name.

What is the difference between static and non static in C?

Non-static classes, also known as instance classes, can be instantiated and contain both static and instance members.
They are useful for representing objects that have a specific state and behavior.
On the other hand, static classes are classes that cannot be instantiated and contain only static members.

Unlike global functions in C, access to static functions is restricted to the file where they are declared. Therefore, when we want to restrict access to functions, we make them static. Another reason for making functions static can be the reuse of the same function name in other files.
