Explicit type conversions
Be accurate with explicit type conversions. They may change the logic of the program execution when types change their capacity of cause the loss of significant bits. It is difficult to adduce typical examples of errors related to the explicit type conversion for they are very different and specific for different programs. You have become acquainted with some errors related to the explicit type conversion earlier.
