How can I write this switch in C++?

How can I write


if(x%26gt;1 %26amp;%26amp; x%26lt;3)


{


statement;


}


with just a switch in C++ without using any of (if) structures! x is a double or a float not an integer





Thanks

How can I write this switch in C++?
is far as my expirence goes you cannot use floating point numbers in a switch statement and expect stable results.


Since there are many stages between 1 and 2 with floating point numbers you'd have to try to cover each one of these cases in a switch statement. Going with if structures will be far more reliable. I have only ever seen and used switch statements used with integers. Infact im pretty certain that you'll at the very least get a warning from the compiler if you try to use a float or double in a switch statement.
Reply:Use this:





switch( (int)(Math.abs(x-2)) )


{


case 0:


{ the true condition statements }


break;


default:


break;


}





The case 0 will be used when


abs(x-2) %26lt; 1





Use algebra to expand this


|x-2| %26lt; 1


-1 %26lt; x-2 %26lt; 1


1 %26lt; x %26lt; 3





Which is what you want.
Reply:switch(x)


{


case 2:


statements;


break;





default:


statements;


break;





}
