C++ supports jumps, and in most cases, there are better ways to branch code; however, for completeness, we will cover the mechanism here. There are two parts to a jump: a labeled statement to jump to and the goto statement. A label has the same naming rules as a variable; it is declared suffixed with a colon, and it must be before a statement. The goto statement is called using the label's name:
int main() { for (int i = 0; i < 10; ++i) { std::cout << i << std::endl; if (i == 5) goto end; } end: std::cout << "end"; }
The label must be in the same function as the calling goto.
Jumps are rarely used, because they encourage you to write non-structured code. However, if you have a routine with highly nested loops or if statements, ...
