[Dev-C++] Formula question

[Philip B. <phi...@pb...>]

Hi,
Could anyone tell me the formula which is used to calculate the min and =
max values for a numerical data type of x bytes? Say for instance that I =
use the
sizeof(datatype) function and get the answer 4, which is usually an =
integer, how do I then programatically calculate the min and max values =
for a signed
and unsigned version of the data type respectively.

Thanks in advance.

Regards
