I was searching on google and i couldnt find anywhere the "or" syntax.
i need it for example like this.
if ( ) or ( ) {

}

i know i can check it 2 times but i want the correct syntax

acmiilangr,

I think you want the logical OR operator. The operator is: ||

Similarly, the logical AND operator is: &&

The logical NOT operator is: !

Do not get these mixed up with the bit operators: | & ^
if ((volume > MAX_VOL) || (time > MAX_TIME))``if ((value > 10) && (value < 100))  // value is 11 - 99

if ( x > y || x > z) { var++; }

I don't think you need that extra "( )", as mentioned earlier, but it is a good habit and makes the code cleaner.

Absolutely right. Just as you don't need the '{' and '}' in the example you gave.
