In computer science, run time, run-time, runtime, or execution time is the time during which a program is running (executing), in contrast to other phases of a program’s lifecycle such as compile time, link time, load time, etc.
A run-time error is detected after or during the execution of a program, whereas a compile-time error is detected by the compiler before the program is ever executed. Type checking, storage allocation, code generation, and code optimization are typically done at compile time, but may be done at run time depending on the particular language and compiler.
In certain cases, the execution of a program begins after a loader performed the necessary memory setup and linked the program with any dynamically linked libraries it needs. In some cases a language or implementation will have these tasks done by the language runtime instead, though this is unusual in mainstream languages on common consumer operating systems.
Some program debugging can only be performed (or is…
