Answer 1

Just because the compiler considers it to be of the 'double' data-type, thus there's a loss of data while implicit casting of a higher data-type (double) to a lower data-type (float). Using the character f or F tells the compiler that it is a floating point literal.

Alternatively, you can do:

float a = (float) 5.55;
