Formally, the goto statement is never necessary, and in practice it is almost always easy to write code without it.. Nevertheless, there are a few situations where gotos may find a place.The most common is to abandon processing in some deeply nested structure, such as breaking out of two or more loops at once. C# goto (With Examples) - Programiz Here, label is an identifier. When goto label; is encountered, the control of the program is transferred to label:. Then the code below label: is executed.

EOF goto - Arduino Reference The use of goto is discouraged in C programming, and some authors of C programming books claim that the goto statement is never necessary, but used judiciously, it can simplify certain programs. The reason that many programmers frown upon the use of goto is that with the unrestrained use of goto statements, it is easy to create a program with undefined program flow, which can never be debugged. c++ - How to store goto labels in an array and then jump to them ... In plain standard C, this not possible as far as I know. There is however an extension in the GCC compiler, documented here, that makes this possible.
