I need some help with Logical Operators

Hi
Here is my question:
I need to use a combination of conditions in order to execute the function i want.
I want something like this:

if (value1 <= x && value1 >= y) OR (value1 <= z && value1 >= n);
doTheFunction;
} else {
dontDoTheFunction
}

What is the right way to do this?

Thanks in advance

 

I'd write it slightly different:

if ((value1 <= x) && (value1 >= y)) || ((value1 <= z) && (value1 >= n));
doTheFunction;
} else {
dontDoTheFunction
}

Code (markup):

The extra parens are because I can never remember the rules of presidence and I use the "||" operator by habit because I use several different languages.

 

The extra parens are for stating to perform this first then move onto the other code.

 

Finally it works this way

if ((value1 <= x && value1 >= y) || (value1 <= z && value1 >= n)){
doTheFunction;
} else {
dontDoTheFunction;
}

PHP:

The script need parenthesis but only two sets in oder to group the two conditions.
And i had also forget to put the "{" symbol at the end of the first line. I use ";" instead and this was wrong.

Thank you for your help

 

If you learn the operator precedence, you will be able to optimize your expressions.

actually your in the right way.

occasionally when i do "or" statement specially 2 or more conditions i do it like this

<code>
if condition1 {
do method;
return;
}

if condition2 {
do method;
return;

....
</code>
if the first conditions is satisfied automatically execute the method the cut the process
in that way i can instantly eliminating the process of reading the following conditions.
