Difference between syntax error and runtime error?

Syntax error can be found during compilation. Runtime error can be found only when you are trying to execute your program.

Syntax errors are those which are caused by incorrect usage of the programming language. All programming language compilers are designed to detect and report such errors done by the programmer

Runtime errors are those which are caused by incorrect usage of programming logic. for example a runtime divide method will throw a run time error if the divisor is '0' because numerically you cannot divide a number by 0

What is Runtime Error?

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.

How do I uninstall your operating system to install a new system?

There is no uninstaller for an operating system. To remove an OS, simply format the partition that holds the operating system. If you use a boot manager to choose between different operating systems the software should automatically detect missing operating systems for you.

Why should image files on webpages be compressed?

So that the image downloads quicker in your browser. File size is important in web design and every element of your page has a file size which adds to total download time.

Why the best programmers do not always make the best software managers?

Programmers tend to think like programmers rather than users. So while they may be capable of producing highly complex software, they may not be able to present the software in a user-friendly manner. Thus we have user interface specialists who spend a huge amount of time and vast amounts of money testing user interfaces upon users of varying degrees of ability. They can then present programmers with their findings and modify their software to provide more intuitive interfaces. Even then, they can still get it completely wrong because someone has to program the interfaces for the test subjects, thus the chosen interfaces are simply the best of what could be bad selection of interfaces. The best of the bad is still bad. So interface specialists spend even more time and money improving the test interfaces. Eventually, one hopes, they get it right and the programmer can finally create software that is intuitive.

With graphical user interfaces (GUIs) like Windows, designing interfaces becomes easier because the interface already exists, the programmer simply has to ensure his interface is consistent with those of other programs, thus making it more intuitive because users already familiar with one application's interface can use the same skills to navigate any similar interface. However, this relies on the fact the GUI is well-designed to begin with and anyone who's used Windows knows just how frustrating an interface it can be. Worse, each new version of Windows changes the interface in various ways, removing familiar features or adding new features. hopefully for the better, but not always. The removal of the start button from Windows 8 was particularly frustrating because the GUI was targeted towards touch-screen users -- which is fine unless you don't happen to have a touch-screen. so although the majority of Microsoft programmers are highly-skilled individuals, even they can get it hopelessly wrong. The software itself is of an extremely high quality, but it's not much use if users are constantly frustrated by the inadequacies of the interface. However it would unfair to blame the programmers for a poor interface -- the user-interface specialists are the ones giving the least value for money. But it is money that has to be spent if an interface is to improve.

How do you use command prompt and what does it do?

Command prompt is the new name for MS_DOS prompt or just DOS promt. Before the "point and click" icons we see on our desktop were invented by Bill Gates and the Microsoft Corperation, basic lines of text were used to navigate through your computer. If you look above at the address bar you will notice that the letters also have the character "/" in there. When used in combination with basic text titles, you can make what's called a destination string. A destination string is just like a map is to you and I. "c:/windows/system" tells the computer to start in the "C Drive" and find the "Windows" file and open it. Now the computer looks at the last entry "System" and looks for that file an opens it. This is just an idea of what happens and why. If you would like to learn more, go find a book called MS_DOS for Dummies. It's about as much fun as watching paint dry, but it's the backbone programming to most Microsoft, Unix, and Linux systems. (I know nothing about Mac's)

What is the step by step process of the igneous rock cycle?

In clastic (or detrital) sedimentary rock:

  1. Weathering of an existing body of rock by natural mechanical or chemical means.
  2. Erosion of the weathered particles by wind, water, ice, and gravity.
  3. Deposition of the particles after transportation.
  4. Compaction of the particles by the weight of overlying sediments.
  5. Cementation of the particles by mineral precipitation from surrounding fluids.

How much does steel cost?

What the meaning of cell pointers in Microsoft Excel?

What is mean by text and binary files used in c?

A text file is a file containing human readable characters organized into records (lines) that are separated by the new-line character. The run-time library parses on this basis, and converts carriage-return/line-feed sequences to and from the new-line character as needed. (In a Windows/DOS environment.)

A binary file is a file containing any characters. There is no file based delimiting - all record distinctions are made by the program. (The exception to this is in the IBM (and other?) family of MainFrame computers where logical record sizes are declared in the DCB, and the file is not processed in stream mode.)

What kind of document is a text file that contains the webpage content?

Web pages obviously have links to other pages, but many types of documents support links to other pages. You can put them into many Microsoft applications for example. The links themselves are referred to as hyperlinks.
