What are built in functions in C programming?

How many built-in functions are there in C?

There are two types of function in C programming: Standard library functions. User-defined functions.

What is built-in function as used in programming?

What is the use of pointers in C?

Pointers are used for file handling. Pointers are used to allocate memory dynamically. In C++, a pointer declared to a base class could access the object of a derived class. However, a pointer to a derived class cannot access the object of a base class.

What is static method in Java?

In Java, a static method is a method that belongs to a class rather than an instance of a class. The method is accessible to every instance of a class, but methods defined in an instance are only able to be accessed by that object of a class.
