The structure pointer points to the memory block address where the Structure is stored. It’s used to make complex data structures like linked lists, trees, and graphs. The structure’s members can be accessed using an arrow operator (->). we can declare a struct pointer in the following manner: here, *p represents the pointer. Accessing is […]

Singly Linked List Singly Linked List is a linear and connected data structure made of Nodes. Each node is composed of a variable data where its content (actual value) is stored and a pointer to the next Node (next node location) on the list. The Linked List has a pointer to the first element of this Node […]

An array name is a constant pointer to the array’s first element. As a result, in the declaration marks is a pointer to &marks[0], which is the address of the array marks’s first element. As a result, the following program fragment assigns p as the address of the element of the first marks. After storing […]

In C, a pointer is a variable that stores the address of another variable. This variable can be of any type, including int, char, array, function, or pointer. The pointer’s size is determined by the architecture. However, in 32-bit architecture, a pointer is 2 bytes in size. Pointer Notation Consider the declaration, This declaration tells […]

A union is a particular data type in C that allows several data types to be stored in the same memory address. A union can have numerous members, but only one member can have value at any given time. Unions are a convenient approach to use the same memory region for numerous purposes. Both Structures […]

Typedef in C is used to redefine the name of the existing variable type. It generally increases the readability and convenience of complex data types. Syntax: For instance, consider the following statement in which the type unsigned long int is redefined to be of the type TWOWORDS: Thus, typedef in C provides a short and […]

C allows us to nest one structure within another structure, which allows us to design complicated data types. This type of structure is known as nested structure. For example, we may need to store the result of an entity student in a structure. The attribute result may also have the subparts like subject name, marks, […]

The structure is a user-defined data type in C that allows us to aggregate data of various types. Structure aids in the creation of a more understandable data type. Need for Structure in C: There are times when we need to keep several characteristics of an entity in C. An entity does not need to have […]
