Data Types	Meaning	Size(in bytes)
int	Integer(int a =5;)	2 or 4
float	Floating point(float a=5.3;)	4
double	Double Floating Point(doube distance=45E12)	8
char	Character (char test='h')	1
wchar_t	wide Character (for storing character of size>1byte)	2
bool	Boolean (bool condition=false;)	1
void	Empty (indicates absence of data)	0

The values it can take depends upon the modifier, (signed or unsigned)

If it is unsigned then value it takes goes from - \(2^{{size to +2}{size}-1\)

for signed data type, the varable can store from \(0 - (2.2^{size}-1)\)

We can further modify some fundamental data types by using Data modifiers.
