-# Operators in C++
+# Operator Overloading in C++
 
-Operators in C++ are symbols that perform various operations on data, such as arithmetic, comparison, and logical operations. They are used to manipulate and evaluate expressions and variables.
+Operator overloading in C++ is a feature that allows you to redefine the way operators work for user-defined types (such as classes and structs). It lets you specify how operators like +, -, *, ==, etc., behave when applied to objects of your class.

-Here is a list of the commonly used operator types in C++:

-- **Arithmetic Operators**: These are used for performing arithmetic operations like addition, subtraction, multiplication, and division.
-
-   - `+`: addition
-     ```cpp
-     int sum = 5 + 3; // sum will be 8
-     ```
-   - `-`: subtraction
-     ```cpp
-     int difference = 5 - 3; // difference will be 2
-     ```
-   - `*`: multiplication
-     ```cpp
-     int product = 5 * 3; // product will be 15
-     ```
-   - `/`: division
-     ```cpp
-     int quotient = 15 / 3; // quotient will be 5
-     ```
-   - `%`: modulo (remainder)
-     ```cpp
-     int remainder = 7 % 3; // remainder will be 1
-     ```
-
-- **Comparison (Relational) Operators**: These are used to compare two values and return true or false based on the comparison.
-
-   - `==`: equal to
-     ```cpp
-     bool isEqual = (5 == 3); // isEqual will be false
-     ```
-   - `!=`: not equal to
-     ```cpp
-     bool isNotEqual = (5 != 3); // isNotEqual will be true
-     ```
-   - `<`: less than
-     ```cpp
-     bool isLess = (5 < 3); // isLess will be false
-     ```
-   - `>`: greater than
-     ```cpp
-     bool isGreater = (5 > 3); // isGreater will be true
-     ```
-   - `<=`: less than or equal to
-     ```cpp
-     bool isLessOrEqual = (5 <= 3); // isLessOrEqual will be false
-     ```
-   - `>=`: greater than or equal to
-     ```cpp
-     bool isGreaterOrEqual = (5 >= 3); // isGreaterOrEqual will be true
-     ```
-
-- **Logical Operators**: These operators are used to perform logical operations such as AND (&&), OR (||), and NOT (!) on boolean values.
-
-   - `&&`: logical AND
-     ```cpp
-     bool result = (true && false); // result will be false
-     ```
-   - `||`: logical OR
-     ```cpp
-     bool result = (true || false); // result will be true
-     ```
-   - `!`: logical NOT
-     ```cpp
-     bool result = !false; // result will be true
-     ```
-
-- **Assignment Operators**: These are used to assign values to variables.
-
-   - `=`: simple assignment
-     ```cpp
-     int x = 5; // x gets the value 5
-     ```
-   - `+=`: addition assignment
-     ```cpp
-     int x = 5;
-     x += 3; // x gets the value 8 (5 + 3)
-     ```
-   - `-=`: subtraction assignment
-     ```cpp
-     int x = 5;
-     x -= 3; // x gets the value 2 (5 - 3)
-     ```
-   - `*=`: multiplication assignment
-     ```cpp
-     int x = 5;
-     x *= 3; // x gets the value 15 (5 * 3)
-     ```
-   - `/=`: division assignment
-     ```cpp
-     int x = 15;
-     x /= 3; // x gets the value 5 (15 / 3)
-     ```
-   - `%=`: modulo assignment
-     ```cpp
-     int x = 7;
-     x %= 3; // x gets the value 1 (7 % 3)
-     ```

-These are some of the main operator categories in C++. Each operator allows you to perform specific operations, making your code more efficient and concise.
