   Jul 16, 2020 · Assume you have two int values a, b, and you want to check that a+b doesn't produce overflow or underflow. There are two cases: a ≥ 0 and a ≤ 0. In the first case, you cannot have underflow. You have overflow if b > INT_MAX - a. In the second case, you cannot have overflow. You can have underflow if b < INT_MIN - a.

   What is integer overflow in arithmetic?

   • When it happens in integer arithmetic, it is integer overflow. Integer overflow happens only in arithmetic operations. Type conversion operations, by definition, do not cause overflow, not even when the result can’t fit in its new type. See Integer Conversion.

   How to detect and prevent overflow/underflow errors in C?

   • In the case of C, the GCC compiler provides a set of functions to detect and prevent overflow/underflow errors. These functions do not differentiate between overflows and underflows. In the above snippet, we try to add A and B and store the sum in C. If the sum crosses the integer limits, the function returns true.

   What is an overflow in C?

   • The situation where an integer outside the allowed range requires more bits than can be stored is called an overflow. Similarly, with real numbers, an exponent that is too small to be stored causes an underflow. int, the most common data type in C, is a 32-bit data type. This means that each int is given 32 bits in memory. If I had the variable

   Do unsigned integers overflow?

   • Besides, integer overflow often happens when doing arithmetic (e.g. x * y) in practice rather than with assignments. And unsigned integers don't overflow at all. @P.P "For example, in the case of INT_OF_CHECK, what if a value that's greater than LLONG_MAX or smaller than LLONG_MIN is assigned to an int?"

   Mar 11, 2015 · Integer overflows occur when the result of an arithmetic operation is a value, that is too large to fit in the available storage space. To clarify the problem, I'll introduce the term process register. Process registers represent an amount of storage available in digital processors and its width defines the range of values that can be represented.
