      Description

      Postfix increment and decrement typically involves making a copy of the object being incremented or decremented, whereas its prefix form does not. Therefore the prefix form is usually the more efficient form, and should be preferred.

      Noncompliant Code Example

      void myFunc(int lim)
{
  int i;
  for (i = 0; i < lim; i++)
  {
    // do something
  }
}

      Compliant Solution

      void myFunc(int lim)
{
  int i;
  for (i = 0; i < lim; ++i)
  {
    // do something
  }
}
