 A much clearer expression of intent would be:
 
-    void f(vector<string>& v)
-    {
+```cpp
+void f(vector<string>& v)
+{
     string val;
     cin >> val;
     // ...
     auto p = find(begin(v), end(v), val);  // better
     // ...
-    }

 A well-designed library expresses intent (what is to be done, rather than just how something is being done) far better than direct use of language features.
