+## Remarks
+
 An invalid # character may have been inserted by an incorrect macro that uses the token-pasting operator (##) instead of the stringizing operator (#).

 > static function 'function' declared but not defined
 
+## Remarks
+
 A forward reference is made to a **`static`** function that is never defined.
 
 A **`static`** function must be defined within file scope. If the function is defined in another file, it must be declared **`extern`**.

 > expression did not evaluate to a constant
 
+## Remarks
+
 An expression declared as **`const`** or **`constexpr`** didn't evaluate to a constant at compile time. The compiler must be able to determine the value of the expression at the point it's used.
