Compiler Error C3015

initialization in OpenMP 'for' statement has improper form

A for loop in an OpenMP statement must be fully and explicitly specified.

The following sample generates C3015:

// C3015.cpp
// compile with: /openmp
int main()
{
   int i = 0, j = 10;

   #pragma omp parallel
   {
      #pragma omp for
      for (; i < 0; i += j)   // C3015
      // Try the following line instead:
      // for (i = 0; i < 0; i++)
         --j;
   }
}
