Introduction to C++ Dynamic Binding and User Defined Type Conversions

CS202 4- ‹#›

nImplicit conversions occur when mixed type expressions are evaluated or when the actual arguments in a function call do not match the formal arguments of the function prototype.

nFirst, the compiler tries to apply a trivial conversion.

nIf there is no match, then the compiler attempts to apply a promotion.

nIf there is no match, then the compiler attempts to apply a built-in type conversion.

nIf there is no match, then the compiler attempts to apply a user defined type conversion.

nIf there is no match, the compiler generates an error.
