How To Use C++ Operators With Examples

Operator C++ Language: A C++ Language is a Special operator that is a mathematical operation performed in the C++ language. 

Operator Can be used to solve the mathematical operation Perform logically. The operator has used variables and data calculation.

Types Operator in C++ Language

1. Arithmetic Operator
2. Relational Operator
3. Logical Operator 
4. Assignment operator
5. Bitwise Operator
6. Increment operator
7. Decrement Operator
8. Conditional Operator

Arithmetic Operator: A arithmetic operation is a used mathematical operation performed. It is many operations performed like addition, subtraction, multiplication, and division.

Important Same Other Languages Operator 

👉C Operators 

👉Java Operators 

👉Python Operators

Example of Arithmetic operator in C Language

1.Addition:a+b or 10+10=20
Here a is operands value (+) Addition is operator and b is operands. It can be used for additional operations performed.

2.Subtraction:a-b or 20-10=10
Here a is operands value (-) Subtraction sign is operator and b is operands. It can be used as Subtraction operations performed.

3.Multiplication:a*b or 10*10=100
Here a is operands value (*) Multiplication sign is operator and b is operands. It can be used Multiplication operations performed.

4.Division:a/b or 10/5=2
Here a is operands value (/) Division sign operator and b is operands. It can be used for Division operations performed.

5.Modulas:a%b or 10%3=1
Here a is operands value (%) Modules sign operator and b is operands. It can be used Modules operations performed.

Arithmetic Operator  Table

Sign.           Operation.         Example

(+)              Addition                    (a+b)

(-)               Subtraction              (a-b)

How To  Use Arithmetic Operator 

#include<iostream>

using namespace std;

int main()

{

int x=35

int y=6;

int add,sub,multi,div,mod;

add=x+y;

sub=x-y;

multi=x*y

div=x/y;

mod=x%y;

cout<<"Addition:"<<add<<"\n; 

cout<<"Subtraction:"<<sub<<"\n; 

cout<<"Multiplication:"<<multi<<"\n; 

cout<<"Division:"<<div<<"\n; 

cout<<"Modulus:"<<mod<<"\n; 

} 

*****OUTPUT*****

Addition:41

Subtraction:29

Multiplication:210

Division:5.8333333

Modulus:5

Relational Operator in C++ Language

Relational Operator: Relational operators are used in the comparison is of the two operands.

It can be using equal operands and condition check in this operator. Relational operator very most and useful operator.

Relational Operator  Table

Sign.      Operation.         Example

(==)           Equal To              (a+b)

(!=)           Not Equal To       (a-b)   

(>)            Greater Than       (a*b)

(<)             Less Than           (a/b)

(>=)   Grater than Or Equal  (a%b)

(<=)   Less Than Or  Equal    (a%b)

 

How To Use Relational Operator in C++?

#include<iostream>

using namespace std;

int main()

{

int a=10;

int b=10;

if(a==b)

{

cout<<"value of a and b are equal"<<"\n";

}

if(a!=100)

{

cout<<"value not equal to"<<"\n";

}

if(a>5)

{

cout<<"value a is grater than 5"<<"\n";

}

if(a<50)

{

cout<<"value a is less than 50"<<"\n";

}

if(a>=10)

{

cout<<"value a is grater than or equal to 10"<<"\n";

}

if(a<=10)

{

cout<<"value a is less than or equal to 10"<<"\n";

}

}

*****OUTPUT*****

value of a and b are equal

value not equal to

value a is greater than 5

value a is less than 50

value a is greater than or equal to 10

value a is less than or equal to 10

Logical Operator in C++ Language

Logical Operators: C Language provides three logical operators. logical Operator tests more than one condition to make decisions.

Types of Logical Operator

1.&& AND

2.|| OR

3.!  NOT

1. AND Operator can be used decisions are two values.AND Operator two values are True AND Operator return True.

But two values are anyone False AND Operator return False.

2. OR operator performs a logical condition on two expressions. if or Operator can be two expressions are True OR Operator return true.

But any of the expressions are False OR Operator return True.

3. NOT operator is very easy Operator. it can be used condition are True NOT Operator returns False and condition are False NOT Operator returns True.

How To Use Logical AND Operator in C++?

#include<iostream>

#include<string.h>

using namespace std;

int main()

{

char user[100]="icoderweb";

char pass[100]="123456";

char user1[100];

char pass1[100];

cout<<"Enter username:";

cin>>user1;

cout<<"Enter password:";

cin>>pass1;

if(strcmp(user,user1)==0&&strcmp(pass,pass1)==0)

{

cout<<"Login successfully";

}

else

{

cout<<"invalid username and password";

}

}

*****OUTPUT*****

Enter username:icoderweb

Enter password:123456

Login successfully

How To Use  Logical OR Operator in C++?

How To Use NOT Operator in C++? 

#include<iostream>

using namespace std;

int main()

{

   

int a=100;

cout<<"Not Operator value:"<<,!(a!=100);

return 0;

}

*****OUTPUT*****

Not Operator value:1

Increment Operator in  C++ Language

Increment Operator:Increment Operators are useful operators generally used.like++x and x++ means x=x+1.

pre-increment first add one to the operand and then the result is assigned to the variable on the left.

post-increment first assigns the value to the variable on the left and then increments the operand.

How To Use Increment Operator in C++?

#include<iostream>

using namespace std;

int main()

{

int a=5;

int b=10;

cout<<"pre-increment operator:"<<++a<<"\n;

cout<<"post-increment operator:<<b+1<<"\n;

}

*****OUTPUT*****

pre-increment operator:6

post-increment operator:11

Decrement Operator in  C++ Language

Decrement Operator: A Decrement Operator has used the decrease the value. like --x and x--.

Pre-decrement first less one to the operands and then the result is assigned to the variable on the left.

Post-decrement first assigns the value to the variables on the left and then decrements the operands.

How To Use Decrement Operator in C++? 

#include<iostream>

using namespace std;

int main()

{

int a=5;

int b=10;

cout<<"pre-decrement operator:"<<--a<<"\n;

cout<<"post-decrement operator:"<<b-1<<"\n;

}

*****OUTPUT*****

pre-decrement operator:4

post-decrement operator:9

Bitwise Operator in  C++ Language

Bitwise Operator: A Bitwise operator is an operation performed on the data bit level. the bitwise operator is also shifted bit right to left.
Note: Bitwise operators are not allowed to float and double.

Bitwise Operator  Table

Sign.        Operation.         Example

(&)           Bitwise AND         (a&b)

(|)             Bitwise OR             (a|b)  

 
(<<)         Bitwise LEFT        (a<<2)

(>>)        Bitwise RIGHT      (a>>2)

How To Use Bitwise Operator in C++?

#include <iostream>

using namespace std;

int main()

{

int y=10, x=30;

cout<<"Bitwise AND Operator:"<<(x&y)<<"\n";

cout<<"Bitwise OR Operator:"<<(x|y)<<"\n";

cout<<"Right shift by:"<<(x>>2)<<"\n";

cout<<"Left shift by:"<<(x<<2);

return 0;

}

*****OUTPUT*****

Bitwise AND Operator:10

Bitwise OR Operator:30

Right shift by:7

Left shift by:120

Assignment Operator  Table

Sign.        Operation        Example

(=)            a=b                         (a=b)

(+=)        a+=b                      (a=a+b)   

(-=)         a-=b                       (a=a-b)

(*=)        a*=b                      (a=a*b)

(/=)         a/=b                      (a=a/b)

(%=)          a%=b                   (a=a%b)

How To Use Assignment Operator in C++?

#include <iostream>

using namespace std;

int main()

{

int a=10,b=5;

a+=b;

cout<<"Assignment Addition:"<<a<<"\n;

int a1=10,b1=5;

a1-=b1;

cout<<"Assignment Subtraction:"<<a1<<"\n;

int a2=10,b2=5;

a2*=b2;

cout<<("Assignment Multiplication:"<<a2<<"\n;
