OpenMP Test on Visual Studio
To use OpenMP on Visual Studio IDE, we should set in tools->options like..
Below code is to calculate pi using loop logic.
There are 5 case code.
0 case is for testing, openMP running well or not.
1 case is no treading, else 2~4 case is some different OpenMP threading case.
I am also not friendly with openMP, so I will refer this code when not remember well.
And I will add more useful technical code..

The result image tells us, OpenMP is certainly faster than no threading.

for each, for_each, for auto - concept clean
Clean up the concept through below examples.
1. normal method : for, iterator
2. for auto loop
3. for each loop
4. for_each
refer to this example
It would be better if I could handle the parallel loop.
This is next time.
Thank you.

two types of check sum function
First is intel method.
Second is motorora method.
Check sum used to check for packet confidence in serial communication.
refer to this below code
