Answer: (C) Order may vary from compiler to compiler Solution: Here, Multiplication will happen before the addition, but in which order the functions would be called is undefined. In an arithmetic expression the parenthesis tell the compiler which operands go with which operators but do not force the compiler to evaluate everything within the parenthesis first.

Answer: (C) max = a>b ? a>c?a:c:b>c?b:c Solution: Option A: assignment statements are always return in paranthesis in the case of conditional operator. It should be a>b? (c=30):(c=40);
Option B: it is syntatically wrong.
Option D: syntatically wrong, it should be return(a>b ? a:b);
Option C: it uses nested conditional operator, this is logic for finding greatest number out of three numbers.

Answer: (D) / * + - Solution: Simply called as BODMAS (Bracket of Division, Multiplication, Addition and Subtraction).

How Do I Remember ? BODMAS !

B - Brackets first
O - Orders (ie Powers and Square Roots, etc.)
DM - Division and Multiplication (left-to-right)
AS - Addition and Subtraction (left-to-right)
