Therefore, when we want to restrict access to functions, we make them static. Unlike global functions in C, access to static functions is restricted to the file where they are declared. The вЂњstaticвЂќ keyword before a function name makes it static. What are static functions? What is their use?ДЄns:In C, functions are global by default.

Dangling pointers arise when an object is deleted or deallocated, without modifying the value of the pointer, so that the pointer still points to the memory location of the deallocated memory. Also, we should make a pointer NULL when memory pointed by it is deallocated in the middle of a program.ДЄns: Dangling Pointer is a pointer that doesnвЂ™t point to a valid memory location. Ideally, we should initialize pointers as NULL if we donвЂ™t know their value at the time of declaration. To implement вЂњlinkedвЂќ data structures like linked lists and binary trees.ДЄns: NULL is used to indicate that the pointer doesnвЂ™t point to a valid location. To pass large structures so that complete copy of the structure can be avoided.Д¤.

For achieving pass by reference in C: Pointers allow different functions to share and modify their local variables.ДЈ. When should we use pointers in a C program?Дў.
