What is the difference between type constraints and type casting?
Type constraints limit the types that can be used in generics, while type casting converts one type to another.
Can you give me an example of type constraints in a programming language?
Sure! In C#, you can use where T : class
to constrain a generic type to reference types.
And what about type casting? How does that work?
Type casting allows you to convert an object of one type into another, like converting an int
to a double
.
Are there any risks associated with type casting?
Yes, if you cast an object to an incompatible type, it can lead to runtime errors.
