Floating point numbers when declared
ie., float f = 3.45f;
requires the "f" or "F" appended after the numeral. Now if i declared,
float f1 = -32;
it does not require an "f" or "F" appended after the number. Can anyone explain why?

Because "-32" isn't a floating point number, it's an int, and it's legal to assign an int value to a float. If you wrote "-32." (with a decimal point at the end) you'd find that the "f" was required again.

an integer can be cast to a floating point number without an explicit cast and -32 is an integer.
