When should a type cast not be used? in C programming language

When should a type cast not be used?

A type cast should not be used to override a const or volatile declaration. Overriding these type modifiers
can cause the program to fail to run correctly.
A type cast should not be used to turn a pointer to one type of structure or data type into another. In the
rare events in which this action is beneficial, using a union to hold the values makes the programmer’s
intentions clearer.

Cross Reference:

II.6: When should the volatile modifier be used?
II.8: When should the const modifier be used?
