goto

Currently I am working on a project where goto statements are heavely used. The main purpose of goto statements is to have one cleanup section in a routine rather than multiple return statements. Like below: BOOL foo() { BOOL bRetVal = FALSE; int *p = NULL; p = new int; if (p == NULL) { cout<<" OOM \n"; goto Exit; } // Lot of code... Exit: if(p) { delete p; p = NULL; } return bRetVal; } This makes it much easier as we can track our clean up code at one section in code, that is, after the Exit label. However, I have read many places it's bad practice to have goto statements. Currently I am

I have some code that I absolutely must implement using goto . For example, I want to write a program like this: start: alert("RINSE"); alert("LATHER"); repeat: goto start Is there a way to do that in Javascript? Peter Olson Absolutely! There is a project called Summer of Goto that allows you use JavaScript at its fullest potential and will revolutionize the way you can write your code. This JavaScript preprocessing tool allows you to create a label and then goto it using this syntax: [lbl] <label-name> goto <label-name> For example, the example in the question can be written as follows: [lbl]

What is an alternative function for the goto keyword in Java? Since Java does not have a goto. Padmarag You could use a labeled BREAK statement: search: for (i = 0; i < arrayOfInts.length; i++) { for (j = 0; j < arrayOfInts[i].length; j++) { if (arrayOfInts[i][j] == searchfor) { foundIt = true; break search; } } } However, in properly designed code, you shouldn't need GOTO functionality. Stephen C There isn't any direct equivalent to the goto concept in Java. There are a few constructs that allow you to do some of the things you can do with a classic goto . The break and continue statements

Is there a "goto" statement in bash ? I know It is considered bad practice, but I need specifically "goto". No, there is not; see §3.2.4 "Compound Commands" in the Bash Reference Manual for information about the control structures that do exist. In particular, note the mention of break and continue , which aren't as flexible as goto , but are more flexible in Bash than in some languages, and may help you achieve what you want. (Whatever it is that you want . . .) If you are using it to skip part of a large script for debugging (see Karl Nicoll's comment), then if false could be a good option

I've long been under the impression that goto should never be used if possible. While perusing libavcodec (which is written in C) the other day, I noticed multiple uses of it. Is it ever advantageous to use goto in a language that supports loops and functions? If so, why? Chris Gillum There are a few reasons for using the "goto" statement that I'm aware of (some have spoken to this already): Cleanly exiting a function Often in a function, you may allocate resources and need to exit in multiple places. Programmers can simplify their code by putting the resource cleanup code at the end of the

After doing some reseach on how to break through a secondary loop while (true) { // Main Loop for (int I = 0; I < 15; I++) { // Secondary loop // Do Something break; // Break main loop? } } most people recommended to call the 'goto' function Looking as the following example: while (true) { // Main Loop for (int I = 0; I < 15; I++) { // Secondary Loop // Do Something goto ContinueOn; // Breaks the main loop } } ContinueOn: However; I have often heard that the 'goto' statement is bad practice. The picture below is perfectly illustrating my point: So How bad is the goto statement really, and why?
