 > '*class*' : constructor syntax missing formal parameters
 
+## Remarks
+
 The constructor for the class does not specify any formal parameters. The declaration of a constructor must specify a formal parameter list. The list can be empty.
 
 To fix this issue, add a pair of parentheses after the declaration of *class*::**class*.

+
 You cannot define a type in the operand field of the **`new`** operator. Put the type definition in a separate statement.

 > 'identifier' : cannot use 'new' to allocate a reference
 
+## Remarks
+
 A reference identifier was allocated with the **`new`** operator. References are not memory objects, so **`new`** cannot return a pointer to them. Use the standard variable declaration syntax to declare a reference.

 > cannot define an anonymous type inside parentheses
 
+## Remarks
+
 An anonymous structure, union, or enumerated type is defined inside a parenthetical expression. This is invalid in C++ because the definition is meaningless in function scope.

 > cannot allocate an array of constant size 0
 
+## Remarks
+
 An array is allocated or declared with size zero. The constant expression for the array size must be an integer greater than zero. An array declaration with a zero subscript is legal only for a class, structure, or union member and only with Microsoft extensions ([/Ze](../../build/reference/za-ze-disable-language-extensions.md)).
