Compiler Error C3046

Missing structured block in an OpenMP '#pragma omp sections' region

A sections directive has an empty code block.

The following sample generates C3046:

// C3046.cpp
// compile with: /openmp /c
#include "omp.h"

int main() {
   int n2 = 2, n3 = 3;

   #pragma omp parallel
   {
      ++n2;

      #pragma omp sections
      {
/*
         ++n2;

         #pragma omp section
         {
            ++n3;
         }
*/
       }   // C3046 uncomment code to resolve this C3046
   }
}
