Answers and Solutions

Answer

Arithmetical operators are functions that take numbers as arguments and map onto a new number.

example: /,*,+,*,%,=,++,--

Logical operators are functions that take propositions (or whatever that can have only two different values, such as ‘true’ or ‘false’) and map them onto either one of those values. So the domain only contains two different things (typically ‘true’ and ‘false’).

example: &&,||, ! ..(AND/OR/NOT)

Answer

Answer

Answer

• logical operator return value 0 or 1.
• arithmetic operator take numeric value as their operands and return a single numerical value.

Answer

Answer

Arithmetic Operators:

There are following arithmetic operators supported by C language:

Operator

Description

+

Adds two operands

-

Subtracts second operand from the first

*

Multiply both operands

/

Divide numerator by denumerator

%

Modulus Operator and remainder of after an integer division

++

Increment operator, increases integer value by one

--

Decrement operator, decreases integer value by one

Logical (or Relational) Operators:

Operator

Description

Example

==

Checks if the value of two operands is equal or not, if yes then condition becomes true.

(A == B) is not true.

!=

Checks if the value of two operands is equal or not, if values are not equal then condition becomes true.

(A != B) is true.

> 

Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.

(A > B) is not true.

< 

Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.

(A < B) is true.

>=

Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.

(A >= B) is not true.

<=

Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.

(A <= B) is true.

&&

Called Logical AND operator. If both the operands are non zero then then condition becomes true.

(A && B) is true.

||

Called Logical OR Operator. If any of the two operands is non zero then then condition becomes true.

(A || B) is true.

!

Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.

!(A && B) is false.

Answer

The logical OR operator ( ) returns the boolean value true if either or both operands is true and returns false otherwise. The operands are implicitly converted to type bool prior to evaluation, and the result is of type bool. Logical OR has left-to-right associativity.

Division. % (Modulo) Returns the integer remainder of a division. For example, 12 % 5 = 2 because the remainder of 12 divided by 5 is 2. The plus (+) and minus (-) operators can also be used to perform arithmetic operations on datetime and smalldatetime values.
