7. Scope pitfalls

• Increasing the nesting of scopes invites shadowing and makes code harder to understand.

• Some partial solutions:

  • Avoid using global scope whenever possible

  • Use a naming convention to indicate the scope of variables. For example, class member variable naming convention might be:

  
      class Point
      {
          int m_x; // Indicate member with m_ prefix
          int m_y;
          //...
      };
