 For more information, see [2.4.1 for Construct](../../../parallel/openmp/2-4-1-for-construct.md), [2.4.2 sections Construct](../../../parallel/openmp/2-4-2-sections-construct.md), and [2.4.3 single Construct](../../../parallel/openmp/2-4-3-single-construct.md).  
  
## Example  
  
```  
// omp_nowait.cpp  
// compile with: /openmp /c  
#include <stdio.h>  
  
#define SIZE 5  
  
void test(int *a, int *b, int *c, int size)   
{  
    int i;  
    #pragma omp parallel  
    {  
        #pragma omp for nowait  
        for (i = 0; i < size; i++)  
            b[i] = a[i] * a[i];  
  
        #pragma omp for nowait  
        for (i = 0; i < size; i++)  
            c[i] = a[i]/2;  
    }  
}  
  
int main( )   
{  
    int a[SIZE], b[SIZE], c[SIZE];  
    int i;  
  
    for (i=0; i<SIZE; i++)  
        a[i] = i;  
  
    test(a,b,c, SIZE);  
  
    for (i=0; i<SIZE; i++)  
        printf_s("%d, %d, %d\n", a[i], b[i], c[i]);  
}  
```  
  
```Output  
0, 0, 0  
1, 1, 0  
2, 4, 1  
3, 9, 1  
4, 16, 2
