TheCHAR BYTEdata type is an alias for theBINARYdata type. This is a compatibility feature. MySQL permits you to create a column of typeCHAR(0). This is useful primarily when you must be compliant with old applications that depend on the existence of a column but that do not actually use...

These pointers point to functions rather than some data type like int, char, etc. We cannot allocate or deallocate memory in the case of function pointers. The following is the syntax for the declaration of a function pointer in C:
