There is a specific order in which they are processed.

Very similar to this:

Код:

5 + 6 * 7 = 47

is not the same as

Код:

(5 + 6) * 7 = 77

The same can be said about conditions. Some expressions are meant to be concatenated.

Код:

if(3 <= strlen( inputtext ) <= 20)

will check if strlen(inputtext) is greater than or equal to 3 and smaller than or equal to 20.

With the additional brackets and the exclamation mark, this will negate the outcome of this check. So this:

Код:

if(! (3 <= strlen( inputtext ) <= 20))

will check if strlen(inputtext) is NOT in the specified range.

Same for expressions where AND and OR are used at the same time, there is a specific order and when it's not respected the outcome will be totally different.

So this:

Код:

if(var1 == 3 && var2 == 4 || var == 4 && var2 == 3)

is very different from this:

Код:

if((var1 == 3 && var2 == 4) || (var == 4 && var2 == 3))

The first one will not accept any values, as the check will fail at the second AND.

The second code will accept 3 & 4 OR 4 & 3 respectively.
