For AND, if first is false then other conditions aren't checked.

For OR, if the first condition is correct then the rest of the conditions aren't checked.

Answer 1

Short circuit rule will be follow here

When 1st condition is true, it will not check for any other condition

So, a=1 is true, that is why condition for b will not be checked

Answer will be a=1,b=1 will be printed here

Answer 2

due to OR if a=1 then no need to check b............

Answer 3

Compiler see if the first condition is true than it does not check for the second condition that's why not decrement

Answer 4

In C, there are 4 operators which clearly specify the order of evaluation of operands

1) logical AND (&&) :- evaluation order is left to right and if left operand is false then second operand is not evaluated

2) logical OR (||) :- evaluation order is left to right and if left operand is true then second operand is not evaluated

3) Ternary Operator (e1?e2:e3): evaluation order is left to right and only one of the operands (e2 or e3) evaluated based on e1

4) Comma Operator(,) : evaluation order is left to right
