what is run time error??

Question

what is this run time error seen in computers??

Answer 1

In computer science, runtime or run time describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). The term is also used as a short form when referring to a runtime library (without a space), a program or library of basic code that is used by a particular computer language to manage a program written in that language while it is running.

A runtime environment is a virtual machine state which provides software services for processes or programs while a computer is running. It may pertain to the operating system itself, or the software that runs beneath it.

In most cases, the operating system handles loading the program with a piece of code called loader, doing basic memory setup and linking the program with any dynamically linked libraries it references. 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 are more efficient or accurate) when performed at runtime. Logical errors and array bounds checking are examples. For this reason, some programming bugs are not discovered until the program is tested in a "live" environment with real data, despite sophisticated compile-time checking and pre-release testing. In this case, the end user may encounter a runtime error message.

A runtime library is a collection of utility functions which support a program while it is running, working with the operating system to provide facilities such as mathematical functions, input and output. These make it unnecessary for programmers to continually rewrite basic capabilities specified in a programming language or provided by an operating system.

Early runtime libraries such as that of Fortran provided such features as mathematical operations. Other languages add more sophisticated memory garbage collection, often in association with support for objects.

More recent languages tend to have considerably larger runtimes with considerably more functionality. Many object oriented languages also include a system known as the "dispatcher" and "classloader". The Java Virtual Machine (JVM) is an example of such a runtime: It also interprets or compiles the portable binary Java programs (bytecode) at runtime. The .NET framework is another example of a runtime library.

Exception handling is one language feature designed to handle runtime errors, providing a structured way to catch completely unexpected situations as well as predictable errors or unusual results without the amount of inline error checking required of languages without it.

Example: A program written in Java, would receive services from the Java Runtime Environment by issuing commands from which the expected result is returned by the Java software. By providing these services, the Java software is considered the runtime environment of the program. Both the program and the Java software combined request services from the operating system. The operating system kernel provides services for itself and all processes and software running under its control. The Operating System may be considered as providing a runtime environment for itself.

Answer 2

It depends on what program said "run time error", but usually it means that...well...an error happened while the program was running.
Usually the program will say what caused the error or what kind of run time error it is (there are several kinds). If the program doesn't say, it means the program doesn't know how to describe the error in a way that an average person can understand (i.e. you would need to be a programmer of the program to understand it.)

When you have developed an application which is working fine in your computer. But when you are trying on another computer it is giving some error due missing of components, files, as well as OS environment is not favour of your program then your program will show error and after that will be shutdown......

This is called Run Time error in my Shot of knowlege

Answer 4

A runtime mistakes as hostile to a syntax mistakes is an mistakes that takes position at the same time as your compiler is going through the code and attempting to execute it. Syntax mistakes can oftentimes be referred to bu maximum programming ecosystem. case in point in case you try to apply a variable non declared. yet in case you declare an integer and later on attempt to bypass it a glide, you receives an mistakes. The IDE have not way of telling till the cost is definitely being handed. the thanks to fix it? i'm no longer particular what ecosystem you're utilising yet maximum IDE comme with a step-through debugger. Use it to discover the problem. desire this help or you'll get slightly more beneficial particular to get particular solutions.

Nice way of saying "untested, uncaptured program error"
