The syntax of typedef is as follows: typedef: It is a keyword. data_type: It is the name of any existing type or user defined type created using structure/union. WebIn C and C++, the line above represents a forward declaration of a function and is the function's prototype.After processing this declaration, the compiler would allow the program code to refer to the entity printThisInteger in the rest of the program.

WebJul 27, 2024 · A linked list is a linear data structure where each element, called a node, is connected to the next element through a pointer. In a singly linked list, each node contains a data item and a pointer to the next node in the list. The order of the list is determined by the pointers, and the first node is called the head while the last node is called the tail. If the …
