Question - How can you determine the maximum value that a numeric variable can hold?
Answer -
For integral types, on a machine that uses two’s complement arithmetic (which is just about any machine you’re likely to use), a signed type can hold numbers from 2(number of bits 1) to +2(number of bits 1) 1. An unsigned type can hold values from 0 to +2(number of bits) 1. For instance, a 16-bit signed integer can hold numbers from 2^15 (32768) to +2^15 1 (32767).
