Dear All,

 

Can I use the expression as below? Meaning can I use || the OR operaror in the expression?

while ((PA<=20 && PA>0) || (PA>=-20 && PA<0))

.........

 .......

 

Thanks

Yes, that is perfectly valid, but I would suggest (as a personal opinion) that you add a few extra parenthesis, in order to make the Precedence Rules more explicit and apparent which will prevent accidental logic bugs in the future.

while( ( ( PA >    0 ) && ( PA <= 20 ) ) ||
       ( ( PA >= -20 ) && ( PA <   0 ) )    )
{
   // ...
}

The above code is just my personal style. There is nothing wrong with your code and it is completely valid!
