value type

When we create variable using data types as int, bool, struct, enumeration this all target to direct value.

The value type consist two main categories:

1. Struct
2. Enumeration

Struct has following categories:

1. Integer types
2. floating point types
3. decimal
4. bool
5. User defined struct

This all are stored value into heap memory.

A value type cannot contain null value but the null-able type does allow value type to be a null.

Each value type has an implicit default constructor that initializes the default value of that type.

Value type	Default value
bool	false
byte	0
char	'\0'
decimal	0.0M
double	0.0D
enum	The value produced by the expression (E)0, where E is the enum identifier.
float	0.0F
int	0
long	0L
sbyte	0
short	0
struct	The value produced by setting all value-type fields to their default values and all reference-type fields to null.
uint	0
ulong	0
ushort	0
