 In C++, data types are used to categorize different types of data that a program can process. They are essential for determining the type of value a variable can hold and how much memory space it will occupy. Some basic data types in C++ include integers, floating-point numbers, characters, and booleans.
 
-Fundamental Data Types
-----------------------
+## Fundamental Data Types
 
-Integer (int)
--------------
+### Integer (int)
 
 Integers are whole numbers that can store both positive and negative values. The size of `int` depends on the system architecture (usually 4 bytes).

 *   long (`long int`): Larger range than `int`.

-Floating-Point (float, double)
-------------------------------
+### Floating-Point (float, double)
 
 Floating-point types represent real numbers, i.e., numbers with a decimal point. There are two main floating-point types:

 Characters represent a single character, such as a letter, digit, or symbol. They are stored using the ASCII value of the symbol and typically occupy 1 byte of memory.

 Booleans represent logical values: `true` or `false`. They usually occupy 1 byte of memory.

-Derived Data Types
-------------------
+## Derived Data Types
 
 Derived data types are types that are derived from fundamental data types. Some examples include:
 
-Arrays

+### Arrays
 
 Arrays are used to store multiple values of the same data type in consecutive memory locations.

 Pointers are used to store the memory address of a variable.

 References are an alternative way to share memory locations between variables, allowing you to create an alias for another variable.

-User-Defined Data Types
------------------------
+## User-Defined Data Types
 
 User-defined data types are types that are defined by the programmer, such as structures, classes, and unions.
 
-Structures (struct)
--------------------
+### Structures (struct)
 
 Structures are used to store different data types under a single variable and accessibility of member variables and methods are public.

 Classes are similar to structures, but the accessibility of the member data and function are governed by access specifiers. By default access to members of a class is private.
