 # Compiler Error C2556
 
-'identifier' : overloaded functions only differ by return type
+> '*function1*': overloaded function differs only by return type from '*function2*'
+
+## Remarks
 
 The overloaded functions have different return types but the same parameter list. Each overloaded function must have a distinct formal parameter list.
 
-The following sample generates C2556:
+## Example
+
+The following example generates C2556:
 
 ```cpp
 // C2556.cpp
 // compile with: /c
-class C {
-   int func();
-   double func();   // C2556
-   int func(int i);   // ok parameter lists differ
-};
+int func();
+double func();     // C2556
+int func(int i);   // OK parameter lists differ
