在需要跳出的外层循环之前,给外层循环添加一个标签,例如: outer_loop: for (int i = 0; i < 10; i++) { for (int j = 0; j < 10; j++) { if (condition) { break outer_loop; } } } 复制代码 在内层循环中使用break语句时,加上外层循环的标签即可实现跳出外层循环的功能。 注意:使用带有...
在上述代码中,我们在外层循环前使用了一个标签`outer_loop`,并在内层循环的break语句中指定了这个标签。这样,当内层循环的break语句执行时,它会跳出外层循环,从而提前结束所有的循环。 总结来说,C语言中循环嵌套的break语句可以用于提前结束当前所在的循环,并跳出外层循环。如果需要跳出多层循环,可以使用标签来标记外层...
