Answer / sathish, cognizant

Any unary expression is considered a cast expression.
The compiler treats cast-expression as type type-name after
a type cast has been made.
Casts can be used to convert objects of any scalar type to
or from any other scalar type.
Explicit type casts are constrained by the same rules that
determine the effects of implicit conversions.
Additional restraints on casts may result from the actual
sizes or representation of specific types.
