 A variable used in an operation is defined with a specified modifier that prevents it from being modified without detection by the compiler. The expression is compiled without modification.
 
 This warning can be caused when a pointer to a **`const`** or **`volatile`** item is assigned to a pointer not declared as pointing to **`const`** or **`volatile`**.
 
 This warning is issued for C programs. In a C++ program, the compiler issues an error: [C2440](../../error-messages/compiler-errors-1/compiler-error-c2440.md).
