Article Introduction：Type qualifiers add special properties to existing data types in the C programming language. There are three type qualifiers in C language, among which volatile and restricted type qualifiers are explained as follows - VolatileA The volatile type qualifier is used to tell the compiler that variables are shared. That is, if a variable is declared volatile, it can be referenced and changed by other programs (or) entities. For example, volatileintx; restricts this to use with pointers only. It shows that pointers are only the initial way of accessing referenced data. It provides more help for compiler optimization. Sample program The following is a C program for volatile type qualifier - int*ptr&
