Undefined behavior - In computer programming, undefined behavior (UB) is the result of executing computer code whose behavior is not prescribed by the language specification to which the code adheres, for the current state of the program. The behavior of some programming languages—most famously C and C++—is undefined in some cases.

Undefined Behavior in C and C++ - Undefined behaviors may also cause security vulnerabilities, especially due the cases when array out of bound is not checked (causes buffer overflow attack). C and C++ have undefined behaviors because it allows compilers to avoid lots of checks.

What Every C Programmer Should Know About Undefined Behavior - Advantages of Undefined Behavior in C, with Examples. Signed integer overflow: If arithmetic on an 'int' type (for example) overflows, the result is undefined. One example is that "INT_MAX+1" is not guaranteed to be INT_MIN.
