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.
