This combination of factors almost always leads to some kind of software bug. It's not that programmers are malicious, stupid or lazy ... it's just that in the rush to meet a deadline we often don't forsee every possible thing that a user can do to our programs and something is bound to happen. In this respect error handling serves two purposes. First, it lets the user know, in a relatively friendly manner, that something has gone wrong and that they should contact the technical support department or that someone from tech support has been notified. As we all know there's a HUGE difference between receiving a rather nasty, tech riddled notice that says something like "Object not set to reference of an object" etc. ... and receiving a nice popup type window that says "There has been

To execute, they have to be compiled or interpreted. An IDE (integrated development environment) is used to write code, test for error handling errors and translate a program. Revise Test < > 1 2 3 4 5 6 5 of 6 Errors There are different types of errors, or bugs, which can prevent computer programs from working in the way they should. Three of the key error types are runtime, syntax and semantic. Runtime errors Runtime errors are errors which will cause handling in c the program or computer to crash even if there appears to be nothing wrong with the program code. Running out of memory will often cause a runtime error. This could be because instructions have been written in the wrong order. Syntax errors Syntax errors are mistakes in the way that the code is written. Translators can only execute a program if it is syntactically correct. Common syntax errors include spelling mistakes, incorrect use of punctuation and the use of capital letters. QQuestion This is a piece of Python code designed to add two numbers together and display the result: first = input("Input the first number ") second = imput("Input the second number ") print("The sum is,First+secnd) There are four syntax errors. Can you identify them? AAnswerReveal answerHide answer The syntax errors are: Line two - input is misspelt as imput Line three - First is written with a capital F, but should be a small f Line three - secnd is a misspelling of second Line three - missing quote mark - it should be "The sum
