c++ - What are the names of type(myVar) and (type)myVar? Are they both bad practice? -

Almost one

but I want to know:

What are these types What is the name and they are 'bad'?

Type (myVar) is a constructor like the creator, but for the original type it is similar to the C-style which is considered bad in C ++?

(type) myVar This is definitely a C-style artist and should it behave like this?

I have seen some examples, where people replace int (a) with (int) a , it cites That the C-style version is bad / wrong, the link has been linked so far, the question says that they are both the same!

What is the name of these types

< Code> (type) (XPR)

• Type (XPR) is known as function-style cast.
• is known as a C-style artist.

And are they 'bad'?

First off, both mentally perfectly equivalent. They are "bad" because they are not safe - they can be equivalent to a static_cast , but evenly a reinterpret_cast , and both types and type expr it is impossible to say ¹ In some cases they also ignore the access specifier (C-Style is a private heritage grade Casting is allowed inside) Also, they are not verbose in the form of a clear C ++ style, which is a After the worst thing that commonly placed to be generally means standing in C ++ and . Consider

¹ int (x) : x depending on the type, it is either Is a static_cast (for example auto x = 4.2f; ) or a reinterpret_cast (for example auto x = nullptr; on an architecture where int is enough an indicator).
