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.
