While performing this translation of technical errors into meaningful user messages, specific errors are often grouped into more generic errors, and this process can lead to user messages becoming so useless that the user doesn't know what went wrong or how to fix it.
Off-by-one errors are common in using the C library because it is not consistent with respect to whether one needs to subtract 1 byte – functions like fgets() and strncpy will never write past the length given them (fgets() subtracts 1 itself, and only retrieves (length − 1) bytes), whereas others, like strncat will write past the length given them.

In Python, objects are reference types. Since Python is not a purely functional language like Haskell, functions can make side effects. 7 Python mistakes all beginner developers make — and how ...
They are also difficult to program with correctly, as asynchronous exceptions must be blocked during cleanup operations to avoid resource leaks. Programming languages typically avoid or restrict asynchronous exception handling, for example C++ forbids raising exceptions from signal handlers, and Java has deprecated the use of its ThreadDeath ...

In computing, a roundoff error, [1] also called rounding error, [2] is the difference between the result produced by a given algorithm using exact arithmetic and the result produced by the same algorithm using finite-precision, rounded arithmetic. [3]
