This article contains C programming syntaxes and equations that behave in a strange way.
Logical && and logical ||
When using the logical AND (&&) or the logical OR (||) the expression is evaluated from left to right. Consider the following code.
i=1;
j=8;
if (( i == 0 ) && (( j++ ) > 0 )) {
...code...
}
The statement of the left side of && evaluates to false the rigth side of the statement is never evaluated - and j is never incremented.
