C++ LANGUAGE VARIABLES 

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.
