 A **`void`** pointer is assigned to a nonvoid pointer by implicit conversion. You must use an explicit cast.

 > 'base_function': overriding virtual function return type differs from 'override_function'

 A function in a derived class attempted to override a virtual function in a base class, but the derived class function did not have the same return type as the base class function.  An override function signature must match the signature of the function being overridden.

 > '*class1*::*function1*': overriding virtual function return type differs and is not covariant from '*class2*::*function2*'
 
-A virtual function and a derived overriding function have identical parameter lists but different return types.

 ## Remarks
 
+A virtual function and a derived overriding function have identical parameter lists but different return types.
+
 In C++, an overriding function in a derived class can't differ only by return type from a virtual function in a base class.
 
 There's an exception to this rule for certain return types. When a derived class overrides a public base class, it may return a pointer or reference to the derived class instead of a base-class pointer or reference. These return types are called *covariant*, because they vary together with the type. This rule exception doesn't allow covariant reference-to-pointer or pointer-to-pointer types.

 > 'identifier' : private and protected members cannot be initialized without a constructor

 Only members and friends can assign a value to a private or protected member. Nonpublic members should be initialized in the class constructor.

 > 'identifier' : no copy constructor available or copy constructor is declared 'explicit'
 
+## Remarks
+
 A copy constructor initializes an object from another object of the same type. (It makes a copy of the object.) The compiler generates a default copy constructor if you do not define any constructors.
