Syntax of C Pointers
The syntax of pointers is similar to the variable declaration in C, but we use the ( * ) dereferencing operator in the pointer declaration.
datatype * ptr;
where
- ptr is the name of the pointer.
- datatype is the type of data it is pointing to.
The above syntax is used to define a pointer to a variable. We can also define pointers to functions, structures, etc.
C Pointers
Pointers are one of the core components of the C programming language. A pointer can be used to store the memory address of other variables, functions, or even other pointers. The use of pointers allows low-level memory access, dynamic memory allocation, and many other functionality in C.
In this article, we will discuss C pointers in detail, their types, uses, advantages, and disadvantages with examples.
