I have an if statement that has two conditions, one is cheap to test, the other is comparatively expensive. If I separate them with an && and the first one fails, will it immediately pass over that if statement, or will it test the second condition anyway? In the case of the latter ...
The truth table is a way to represent the truth values of a logical expression. We can determine if the resultant value of an expression will be True or False
Operator associativity is thedirectionfrom which an expression is evaluated. For example, inta =1;intb =4;// a will be 4a = b; Take a look ata = 4;statement. The associativity of the=operator is from right to left. Hence, the value ofbis assigned toa, and not in the other directio...
