How are pointers defined in the C language?

In the C language, pointers can be defined using the following syntax:

Pointer variable name of data type.

Data types represent the type of data that a pointer points to, which can be basic data types, structures, arrays, etc. The pointer variable name can be customized as needed.

For example, define a pointer variable numPtr that points to an integer.

A pointer to an integer called numPtr.

In this example, int indicates that the data type pointed to by the pointer is an integer, * signifies that the variable is a pointer, and numPtr is the name of the pointer variable.

It is important to note that when defining a pointer variable, the data type the pointer is pointing to must be specified, otherwise the compiler will not be able to allocate the correct memory space.
