Floating point types and void type

Floating Point Types :
Floating point number represents a real number with 6 digits precision. Floating point numbers are denoted by the keyword float. When the accuracy of the floating point number is insufficient, we can use the double to define the number. The double is same as float but with longer precision. To extend the precision further we can use long double which consumes 80 bits of memory space.



Void Type :
Using void data type, we can specify the type of a function. It is a good practice to avoid functions that does not return any values to the calling function.
