Use the return keyword to exit from a method. From the Java Tutorial that I linked to above: Any method declared void doesn’t return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow … Read more
Use break: However, if your code looks exactly like you have specified you can use a normal while loop and change the condition to obj != null:
Because your else isn’t attached to anything. The if without braces only encompasses the single statement that immediately follows it. Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered. In addition, using a switch here would make more sense. Note that instead of an infinite for loop I used a while(boolean), making it … Read more
To break a $.each or $(selector).each loop, you have to return false in the loop callback. Returning true skips to the next iteration, equivalent to a continue in a normal loop.
The way it looks I think you’re not in a loop but just checking args in main. You probably want something like return 1 or exit(1) instead of the break.
break is to break out of a loop like for, while, switch etc which you don’t have here, you need to use return to break the execution flow of the current function and return to the caller. Note: This does not cover the logic behind the if condition or when to return from the method, for that we … Read more
if is not a loop structure, so you cannot “break out of it”. You can, however, break out of the foreach by simply calling break. In your example it has the desired effect: Just for completeness for others that stumble upon this question looking for an answer.. break takes an optional argument, which defines how many loop structures it should break. Example: … Read more
The No symbol table loaded message you are getting is misleading: all GDB is telling you is that your binary does not have any debugging info in it. Usually this is solved by rebuilding the binary with -g flag, but since you are given an already compiled and linked file, you can’t do that. Without debug info, certain commands, such as list, break … Read more
