An error that occurs during the execution of a program. In

contrast, compile-time errors occur while a program is

being compiled. Runtime errors indicate bugs in the program

or problems that the designers had anticipated but could do

nothing about. For example, running out of memory will

often cause a runtime error.

A runtime error is a computer error that appears in

the form of a message box consisting of a particular code

along with its corresponding definitions. Usually, a user

will notice that the computer becomes noticeably slow

before a runtime error appears.

After the runtime error message has been displayed and

closed, the software that shows this error would normally

close or freeze. In some cases, the operating system will

reboot.
