40 goto and labels in c

en.wikipedia.org › wiki › GotoGoto - Wikipedia GoTo (goto, GOTO, GO TO or other case combinations, depending on the programming language) is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control. › software › gnu-c-manualThe GNU C Reference Manual You can use goto statements to simulate loop statements, but we do not recommend it—it makes the program harder to read, and GCC cannot optimize it as well. You should use for, while, and do statements instead of goto statements, when possible. As an extension, GCC allows a goto statement to jump to an address specified by a void* variable.

gcc.gnu.org › onlinedocs › gccExtended Asm (Using the GNU Compiler Collection (GCC)) The GotoLabels section in an asm goto statement contains a comma-separated list of all C labels to which the assembler code may jump. GCC assumes that asm execution falls through to the next statement (if this is not the case, consider using the __builtin_unreachable intrinsic after the asm statement).

› lab › cplusRecommended C Style and Coding Standards Suspect labels inside blocks with the associated switch or goto outside the block. Wherever the type is in doubt, parameters should be cast to the appropriate type. Always cast NULL when it appears in non-prototyped function calls. Do not use function calls as a place to do type cheating.

NOTE − Use of goto statement is highly discouraged in any programming language because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify.

The statement immediately followed after ‘label:’ is the destination statement. The ‘label:’ can also appear before the ‘goto label;’ statement in the above syntax.
