Pointers in C - GeeksforGeeks
The void pointers in C are the pointers of type void. It means that they do not have any associated data type. They are also called generic pointers as they can point to any type and can be typecasted to any type.

What are the different types of pointers in C language?
It's defined as an integer constant expression with the value 0, or an expression to the type void *. When this is converted to a pointer type, a null pointer is different from any pointer to an object or function. Following is the syntax for the Null Pointer is as follows ? ... The below example demonstrates how to declare a null pointer and check if it points to any memory location.

Why do we use pointers in C?
We use pointers to access the memory of the said variable and then manipulate their addresses in a program. The pointers provide the language with flexibility and power. They store the addresses of other variables in the program. There are various uses of the pointers in C language. Let us look at some of them: · Dynamic allocation of memory: We can allocate the memory dynamically in C language when we use the calloc() and malloc() functions. The pointers are primarily used in such cases. · Structures, Functions, and Arrays: We generally use the pointers in the C language in the cases of struc

What is the void pointer in C?
The void pointer is also known as the generic pointer in the C language. This pointer has no standard data type, and we create it with the use of the keyword void. The void pointer is generally used for the storage of any variable’s address.

Can a pointer point to another pointer in C?
Yes, that's called a double pointer. You can use it to indirectly modify a pointer or pass pointers to functions.

Pointers in C: Types of Pointers
In C, you must declare a pointer by stating its data type, an asterisk (*), and the name of the pointer variable. As an example, "int *ptr;" declares an integer pointer with the name "ptr".

Line 02 initializes a variable named q and sets it's value to 5. Line 03 uses the & to assign p the "address of variable q". Line 04 sets the "value of the integer pointed to by p" to 10, and since p is pointing to q's memory, q now has the value of 10. This is just an example of what pointers can do.

4 days ago - This declares a variable ptr that stores a pointer to an object of type int. Other types can be used in place of int; for example, bool *ptr would declare a pointer to an object of type bool. After a pointer has been declared, it can be assigned an address. In C, the address of a variable can be retrieved with the & unary operator:

Near pointer means a pointer that is utilized to bit address of up to 16 bits within a given section of that computer memory which is 16 bit enabled. It can only access data of the small size of about 64 kb within a given period, which is the main disadvantage of this type of pointer.

No. They're pointers, whose size is system-dependent and whose only compatible type is void*.

Pointers are of pointer type. If you're asking about how pointer values are represented in memory, that really depends on the platform. They may be simple integral values (as in a flat memory model), or they may be structured values like a page number and an offset (for a segmented model), or they may be something else entirely.

June 13, 2025 - These expressions state that the value 45 is assigned to the variable x, and the pointer “ptr” stores the address of the variable x. The & (addressof) operator is used to obtain the memory address of the variable x. A pointer can also be declared and initialized in a single step. It is called the pointer definition. ... It should be noted that the data type of the variable and the pointer should be the same. The following example illustrates the declaration and initialization of a pointer:

The most common bugs related to pointers and memory management is dangling/wild pointers. Sometimes the programmer fails to initialize the pointer with a valid address, then this type of initialized pointer is known as a dangling pointer in C.
