Define void data type and write any three use of it.

Q : Define void data type and write any three use of it.

The data type void actually refers to an object that does not have a value of any type. Void is also used to indicate when a function does not return a value or no argument. Such a function is used for its side effect and not for its value. In the function declaration and definition, we have indicated that the function does not return a value by using the data type void to show an empty type, i.e. no value. Similarly, when a function has no formal parameters, the keyword void is used in the function prototype and header to signify that there is no information passed to the function.

Q : What is dangling pointer in C? What is wild pointer in C? Give example?

Dangling  Pointer

Dangling or wild is a pointer which does not point valid object. When a pointer has declared it must be assign a valid address memory address otherwise it will point some location which is not valid. These are special cases of memory safety violations. More generally, dangling references and wild references are references that do not resolve to a valid destination.
