Arithmetic Operators

Operators :

Operators are the symbol use to perform any operation.

Operand is the variable or number that use in operation.

Types of Operator

1. Arithmetic Operator : (-, +, /, *, %)
2. Assignment Operator : (=, +=, -=,...)
3. Relational Operator : (>,<,>=,<=,==)
4. Logical Operator: (&&,||, !)
5. Bitwise Operator : (&, |, ^, ~, <<, >>)

1.Arithmetic Operator:

+ ---> Addition
- ---> Subtraction
* ---> Multiplication
/ ---> Division
% ---> Modules

+ Addition operator :

• Addition operator is used to add the two number.

Example 1 : Addition of two numbers

#include <iostream>
using namespace std;

int main() {

    int a=5;
    int b=10;

    int result = a + b;
    cout<<result;

    return 0;
}

Output :

15

Explanation :

Line 5 : initialize the a variable assign value 5.
Line 6 : initialize the b variable assign value 10.
Line 8 : declare result, perform operation a + b and stored in result variable.
Line 9 : print result variable.

- Subtraction operator :

• Subtraction operator is used to find the difference between two number.

Example 2 : Subtraction of two numbers

#include <iostream>
using namespace std;

int main() {

    int a=20;
    int b=10;

    int result = a - b;
    cout<<result;

    return 0;
}

Output :

10

Explanation :

Line 5 : initialize the a variable assign value 20.
Line 6 : initialize the b variable assign value 10.
Line 8 : declare result variable, perform operation a - b and stored in result variable.
Line 9 : print result variable.

* Multiplication operator :

• This operator is used to find the product.

Example 3 : Multiplication of two numbers

#include <iostream>
using namespace std;

int main() {

    int a=55;
    int b=2;

    int result = a * b;
    cout<<result;

    return 0;
}

Output :

110

Explanation :

Line 5 : initialize the a variable assign value 55.
Line 6 : initialize the b variable assign value 2.
Line 8 : declare result variable, perform operation a * b and stored in result variable.
Line 9 : print result variable.

/ division operator :

• It Calculate the questient.

Example 4: Division of two numbers

#include <iostream>
using namespace std;

int main() {

    int a=55;
    int b=2;

    int result = a / b;
    cout<<result;

    return 0;
}

Output :

27

Explanation :

Line 5 : initialize the a variable assign value 55.
Line 6 : initialize the b variable assign value 2.
Line 8 : declare result variable, perform operation a / b and stored in result variable.
Line 9 : print result variable.

% Modulus Operator :

• It calculates reminder after the integer division

Example 5 :

#include <iostream>
using namespace std;

int main() {

    int a = 22;
    int b = 5;

    int result = 22 % 5;
    cout<<result;

    return 0;
}

Output :

4

Explanation :

Line 5 : initialize the a variable assign value 22.
Line 6 : initialize the b variable assign value 5.
Line 8 : declare result variable, perform operation a % b and stored in result variable.
Line 9 : print result variable.

odd number : 3,7,9
odd % 2 = 1
ex:
3 % 2 = 1
7 % 2 = 1
9 % 2 = 1

even number:4,8,10
even % 2 = 0
ex :
4 % 2 = 0
8 % 2 = 0
10 % 2 = 0
