Data Types In C

Now back to some theory , from the previous programs we used something called an int where we declared variables and used a placeholder %d in the printf statements
Now let us look at in in detail . C is a strongly typed language meaning it is strict and when we declare a variable we need to tell C what kind of variable it is (what value will it hold ).
This is known as the Data  Type . Here are a few inbuilt data types in C with some information about them
       Name                Type       Storage Size         Placeholder
  1. Integer             int          2 or 4 bytes           %d
  2. Decimal           float        4 bytes                  %f
  3. Character         char         1 byte                   %c
These are the data types . They can be modified using modifiers about which we will see in later posts

we will be commonly using char , int , float. 

Please note that in this blog we are dealing with C programming from a practical point of view. We are not concerned with in depth knowledge of C but only about how to write your own 
programs using the basics..

In the previous programs we used the int datatype . Which didn't give you correct results during the division operation as it rounded off the quotient . We will look at how we can use other datatypes in the coming posts .. Stay Tuned..................
