## Introduction: Operators in C++

**An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. C++ is rich in built-in operators and provides the following types of operators:**

**1) Arithmetic Operators **

**2) Relational Operators **

**3) Logical Operators **

**4) Bitwise Operators **

**5) Assignment Operators **

**6) Misc Operators **

**This chapter will examine the arithmetic, relational, logical and assignment operators one by one. Others are not needed for beginners......**

## Step 1: Arithmetic Operators

### There are following arithmetic operators supported by C++ language:

1) Addition (+)

2) Subtraction (-)

3) Multiplication (*)

4) Division (/)

5) Modulus (%)

6) Increment (++)

7) Decrement (--)

**They are explained well in the image above.**

## Step 2: Relational Operators

**There are following are Relational Operators in C++ :- **

**SUPPOSE A HOLDS VALUE 10 AND B HOLDS 20**

1) == - Checks whether value of two operands are equal or not, if yes then it becomes true.

** A == B is not true**

2) != - Checks whether value of two operands are unequal or not, if yes then it becomes true.

** A != B is true **

3) < - Checks whether one operand is greater than other or not, if yes then it becomes true.

** A < B is true**

4) > - Checks whether one operand is greater than other or not, if yes then it becomes true.

** A > B is not true**

5) >= - Checks whether left operand is greater than or equal to the other or not, if yes then it becomes true.

** A >= B is not true**

6) <= - Checks whether right operand is greater than or equal to the other or not, if yes then it becomes true.

** A <= B is true**

## Step 3: Logical Operators

There are following logical operators supported by C++ language

**Assume variable A holds 1 and variable B holds 0, then:**

1) && - Called logical AND operator. If both the operands satisfy all the given conditions then it becomes true.

**A == 1 && B == 0 is true BUT A == 0 && B == 0 is not true**

2) || - Called logical OR operator. If both the operands satisfy either of the given conditions then it becomes true.

**A == 0 || B == 0 is true.**

3) ! - Called logical NOT operator. Use to reverse the logical state of an operand. If a condition is true then it becomes false.

**!(A == 1 && B == 1) is true BUT !(A == 1 && B == 0) is not true.**

## Step 4: Assignment Operators

There are following assignment operators supported by C++ language:

1) =

2) +=

3) -=

4) *=

5) /=

6) %=

ok i will keep it in mind the next time

Simple and clean, good for beginers :).

You should explain the differences between pre and post-increment operators "++a" or "a++" as elements in an expresion.

I think the rest of operators should be mentioned even when the instructable is intended for beginers. Operators like << >> , [ ] -> . (cast), etc.
