Datatypes C++

While writing program in any language, you need to use various variables to store various information.
Variables are nothing but reserved memory locations to store values.
This means that when you create a variable you reserve some space in memory.

You may like to store information of various data types like character,
wide character, integer, floating point, double floating point, boolean etc.
Based on the data type of a variable, the operating system allocates
memory and decides what can be stored in the reserved memory.

Primitive Built-in Types
C++ offers the programmer a rich assortment of built-in as well as user defined data types.
Following table lists down seven basic C++ data types −



Several of the basic types can be modified using one or more of these type modifiers −



♣ signed
♦ unsigned
♠ short
♥ long


The following table shows the variable type, how much memory it takes to store the value in memory,
and what is maximum and minimum value which can be stored in such type of variables.



The size of variables might be different from those shown in the above table,
depending on the compiler and the computer you are using.
