To cast, casting
If you want to change the 
datatype of a variable 
you have to use a technic called cast. For example if want to 
change an int to a 
float 
you could use the following syntax:
	main()
        {
          int var1;
	  float var2;
	  var2 =index.html (float)var1;
	}
As it happens this example would never be used in practice because C 
would perform the conversion automatically.
What this example does show is the cast operator () . This states, 
the result of the expression (in this case var1) is to be a  
data type of float.
