1. OPERATORS BY: Kalpana & Milan

7. binary (2 operands) 13 - 7

8. ternary (3 operands) exp1 ? exp2 : exp3 For example: a = b + c; denote an expression in which there are 3 operands a, b, c and two operator + and = .

10. There are two arithmetic unary operators: + and -

11. Examples:

12. x = -y; a = +b; The not logical operator is also a unary operator.

13. Operator & its Use:

14. ! Negation,

15. ++ increment by 1,

16. -- decrement by 1

18. There are several math operators that require two operands: + - * / %

19. Examples: total = x * y + 2;

21. + addition,

22. - subtraction,

23. * multiplication,

24. / division,

25. % remainder division or modulus,

26. = assignment,

27. > greater than,

28. < less than,

29. && AND,

30. || OR

32. There is only one ternary operator that requires three operands.

33. It's the conditional operator:

34. “ ? :”

35. We will study this in Conditional operator.

36. Operator Meaning Example Answer + Addition ans = 7 + 3; 10 - Subtraction ans = 7 - 3; 4 * Multiplication ans = 7 * 3; 21 / Division ans = 7 / 3; 2 % Modulus Operator ans = 7 % 3; 1 Cont... Arithmetic Operators

40. Operator Meaning < less than <= less than or equal to > greater than >= greater than or equal to == equal to != not equal to

42. exp1 relational operator exp2 Where exp1 and exp2 are expressions, which may be simple constants, variables or combination of them. Given below are some examples of relational expressions .

43. 6.5 <= 25 TRUE -65 > 0 FALSE 10 < 7 + 5 TRUE

44. Relational expressions are used in decision making statements of C language such as if, while and for statements.

47. True && True= True False && True= False True && False =False False && False =False

50. ! True =False ! False=True

52. x + = 1 is same as x = x + 1

53. The commonly used shorthand assignment operators are as follows:

54. Statement with simple assignment operator Statement with shorthand operator a = a + 1 a += 1 a = a – 1 a -= 1 a = a * (n+1) a *= (n+1) a = a / (n+1) a /= (n+1) a = a % b a %= b

57. In prefix notation the variable is incremented or decremented first, then the new value is returned.

58. In postfix notation the variable's original value is returned, and the addition or subtraction happens later.

60. Condition ? Expression1 : Expression2;

61. You can think of the conditional operator as if it were a function that works like this:

64. Symbol and their Meaning: ~ Complement & And | Or ^ Exclusive-Or << Left shift >> Right shift

66. The exclusive-OR (XOR), it performs same as logical OR operator: The result is 1 only when either X is equal to 1 or Y is equal to 1, but not when both X and Y are equal to 1.

68. int a[5] = { 1, 2, 3, 4, 5 }; int b = a[3];

69. On the second line the a[3] accesses the fourth element of the array and assigns b to the value 4.
