The short answer is no. You would generally use some higher-order function to express the same functionality. There is a number of functions that let you do this, corresponding to different patterns (so if you describe what exactly you need, someone might give you a better answer). For example, tryFind function returns the first value … Read more
In your example break statement will take you out of while(b) loop while(a) { while(b) { if(b == 10) { break; } } // break will take you here. }
You cannot use break; this way, it must appear inside the body of the for loop. There are several ways to do this, but neither is recommended: you can exit the program with the exit() function. Since the loop is run from main() and you do not do anything after it, it is possible to … Read more
The break statement inside a switch can be used when you don’t need a case to have any actual functionality, but want to include it to make your logic easier or clearer. Suppose for example you want to use a switch statement to determine if a given year is a leap year or not. (This … Read more
Return exits from the entire function. Break exits from the innermost loop. Thus, in a function like so: def testing(target, method) (0..100).each do |x| (0..100).each do |y| puts x*y if x*y == target break if method == “break” return if method == “return” end end end end To see the difference, try: testing(50, “break”) testing(50, … Read more
You can use until to make the loop end. You should give it at the end of the loop. This is useful if you do not need to step in to iterate a loop.
You can just use goto to jump directly to a label. while (somethingA) { // … while (somethingB) { if (condition) { goto label1; } } } label1: // … In C-like languages, goto often ends up cleaner for breaking nested loops, as opposed to keeping track of boolean variables and repeatedly checking them at … Read more
