Correctness is important, yes, and none of the examples checked the
input for range errors (and my example using sscanf can't do that at
all).  But not all languages follow what you call the wrong direction.
For example, the Python code won't fail due to the range of the inputs
(except in extraordinary circumstances) because it uses
multiple-precision integers.

In this particular case, we have little idea what's important.  If the
OP has very large amounts of data, and all the input number are small
like the ones shown, then checking for out of range inputs is going to
be wasted effort.
