Run-error in online compiler
A runtime error is a program error that occurs while the program is running. An error that occurs during the execution of a program. The term is often used in contrast to other types of program errors, such as syntax errors and compile time errors.
There are many different types of runtime errors. One example is a logic error, which produces the wrong output. Another type of runtime error is a memory leak. This type of error causes a program to continually use up more RAM while the program is running. A memory leak may be due to an infinite loop, not deallocating unused memory, or other reasons.
A program crash is the most noticeable type of runtime error, since the program unexpectedly quits while running. Crashes can be caused by memory leaks or other programming errors. Common examples include dividing by zero, referencing missing files, calling invalid functions, or not handling certain input correctly.
