# Compiler Warning (level 4) C4623

'`derived class`' : default constructor was implicitly defined as deleted because a base class default constructor is inaccessible or deleted
> '`derived class`' : default constructor was implicitly defined as deleted

A constructor was not accessible in a base class and was not generated for the derived class. Any attempt to create an object of this type on the stack will cause a compiler error.
Because the default constructor is deleted or inaccessible in a base class, the compiler can't generate a default constructor for the derived class. Attempts to create an object of this type by using the default constructor (for example, in an array) cause a compiler error.

This warning is off by default. See [Compiler Warnings That Are Off by Default](../../preprocessor/compiler-warnings-that-are-off-by-default.md) for more information.
