A: They are following:
Const: point out that memory once initialized, must not be modify through a program.
Volatile: denote that value in the memory location can be modified although nothing in the program code changes the contents. For instance: if you have a pointer to hardware location which contains the time, where hardware modifies the value of this pointer variable and not the program. The intent of this keyword is to get better optimization capacity of the compiler.
Mutable: Denote that particular member of a class or structure can be changed even if a particular structure variable, class, or class member function is constant.
struct data
{
char name[80];
mutable double salary;
}
const data MyStruct = { "Satish Shetty", 1000 };
//initlized by complier
strcpy ( MyStruct.name, "Shilpa Shetty"); // compiler error
MyStruct.salaray = 2000 ; // complier is happy allowed
