編譯器錯誤 C3036

'operator': OpenMP 'reduction' 子句中有無效的運算子語彙基元

備註

未正確指定 reduction 子句。

Example

下列範例會產生 C3036:

// C3036.cpp
// compile with: /openmp
static float a[1000], b[1000], c[1000];
void test1(int first, int last) {
   static float dp = 0.0f;
   #pragma omp for nowait reduction(.:dp)   // C3036
   // try the following line instead
   // #pragma omp for nowait reduction(+: dp)
   for (int i = first ; i <= last ; ++i)
      dp += a[i] * b[i];
}
