   What are integer overflow and integer underflow errors in C?

   • Integer Overflow and Integer Underflow in C, do not raise any errors, but the program continues to execute (with the incorrect values) as if nothing has happened. It makes overflow errors very subtle and dangerous. We will see several methods to detect these errors in this article.

   What is an integer overflow?

   • 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.

   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

   Does integer overflow occur when doing arithmetic?

   • "Besides, integer overflow often happens when doing arithmetic (e.g. x * y) in practice rather than with assignments." - Correct, but that is just one way to proof if an overflow can happen. But one can also use arithmetic expressions as function argument and check.
