Data Types and Variables

 

A data type specifies whether or not a variable can store a number, a single character or text. Variables are names given to the memory location for storing data. Data Types are used to specify the types of values related to variables.

Seven commonly used data types :

Data Type	Use
string	To store string
int	To store integer values
float	To store floating point values
double	To store large floating point values
char	To store a single character
bool	To store the values "true" or "false"
long	To store large integer values

There are many powerful data types but we the little programmers don't need them :D
