Problem Statement

Some languages support one or more integer types of the underlying processor. This integer types have fixed size;   usually   8-bit,   16-bit,   32-bit,   or   64-bit. The integers supported by such a type can be   signed   or   unsigned. Arithmetic for machine level integers can often be done by single CPU instructions. This allows high performance and is the main reason to support machine level integers.

An integer overflow happens when the result of a computation does not fit into the fixed size integer. The result can be too small or too big to be representable in the fixed size integer.

When a language has fixed size integer types, create a program that does arithmetic computations for the fixed size integers of the language. These computations must be done such that the result would overflow. The program should demonstrate what the following expressions do.

For 32-bit signed integers: For 64-bit signed integers: For 32-bit unsigned integers: For 64-bit unsigned integers:

Let's start with the solution:

A% = -(-32767-1)


A% = 20000 + 20000


A% = -32767 -32767


A% = 182 * 182


A% = -32767 : POKE PEEK(131) + PEEK(132) * 256, 0 : ? A%
