Hello reading about the upcoming changes of mql4 there are a few questions I would like to talk about http://forum.mql4.com/57476.

Quote

  1. Changed the priority of AND/OR logical operations. Now, everything is similar to the standard C/C++


Where has been the difference before? Can someone please give me an example.

Quote

  1. Only integer values are now used in switch operator. Real values could have been used before


As much as I remember mql4 only allowed to use integers in switch before.....?

These are pretty irrelevant questions; if in doubt consult documentation or test in code.
What is really interesting about the "upgrade", is that you can have event handling (chart event) and new data types, oop (?) etc.

Yes they may be irrelevant but I am still interested. What to test if I don't know what I am looking for?
If an if statement suddenly returns a different outcome this is not so irrelevant at the end after all.

I understand that; however there is c/c++ documentation freely available and you can look up operator precedence there, and also early exit of boolean test if result is false to the test.
