The above symbols mean the following −
int* - Pointer to int. This one is pretty obvious. int const * - Pointer to const int. int * const - Const pointer to int int const * const - Const pointer to const int
Also note that −
const int * And int const * are the same. const int * const And int const * const are the same.
If you ever face confusion in reading such symbols, remember the Spiral rule: Start from the name of the variable and move clockwise to the next pointer or type. Repeat until expression ends.
