Operator, Operand, and Arithmetic

What are Operator and Operand?

An operator is a symbol to process the values in the result of a new value

An operand is a part that specifies which data should be manipulated or exploited



Example

X = Y + Z  

= and + sign are operators

X, Y and Z are operands

Depending on its type of operation, the operator can be grouped as follows:

Assignment Operator

Used to assign a value to an operand

Syntax:

Operand1 = Operand2;

The left operand (Operand1) must have a value, such as variable

The operand on the right (Operand2) can be a constant, another variable, an expression or

a function.

Example

x=5;

Arithmetic Operator

Example of increment and decrement:

Increment x=1, x++ >>>>x=2

Decrement x=1,x--    >>>>x=0

Relational operator

Used to compare values with True or False

-->

Symbol	Functionality
==	Equality
!=	Not equal
<	Less than
>	Greater than
<=	Less or equal than
>=	Greater or equal than
?:	Conditional assignment

False in C has a value of zero(0)

True in C has a value of one(1)

Conditional Expressions:

if(a > b)  z = a;

else z = b;

can be written as:     z = (a > b) ? a : b;

Logical Operator

Operand in Logical Operator is the operand with the value TRUE or FALSE.

Bitwise operator

Symbol	Meaning	Example
&	AND	A & B
|	OR	A | B;
^	XOR	A ^ B;
~	Complement	~A;
>>	Shift Right	A >> 3;
<<	Shift Left	B << 2;

--> int A=24; int B=35; int C;Example:

C = A & B;  // value C = 0

C = A | B;    // value C = 59

Note:

A=24 binary: 011000

B=35 binary: 100011

Bit by bit AND operation resulting: 000000, in decimal: 0

Bit by bit OR operation resulting : 111011, in decimal: 59

Pointer Operator

Pointer is an operator that uses the symbols "&" and "*" to search the data

addresses and data values of a variable whose uses are:

& = address

* = value of
