一、循环控制

break

continue

二、多重循环

break

• 跳出循环

continue

• 跳出循环这一轮剩下的语句进入下一轮

二、多重循环

• break和continue只能对它所在的那层循环作用。
• 接力break
  • 例子：

#include 

int main()
{
	int x;
	int one, two, five;
	int exit = 0;
	
	scanf("%d", &x);
	
	for ( one = 1; one < x*10; one++ ) {
		for ( two = 1; two < x*10/2; two++ ) {
			for ( five = 1; five < x*10/5; five++ ) {
				if ( one + two*2 + five*5 == x*10 ) {
					printf("可以用%d个1角加%d个2角加%d个5角得到%d元n",
						one, two, five, x);
					exit = 1;
					break;
				}
			}
			if ( exit == 1 ) break;
		}
		if ( exit == 1 ) break;
	}
	
	return 0;	
} 

也可以这么写：

#include 

int main()
{
	int x;
	int one, two, five;
	
	scanf("%d", &x);
	
	for ( one = 1; one < x*10; one++ ) {
		for ( two = 1; two < x*10/2; two++ ) {
			for ( five = 1; five < x*10/5; five++ ) {
				if ( one + two*2 + five*5 == x*10 ) {
					printf("可以用%d个1角加%d个2角加%d个5角得到%d元n",
						one, two, five, x);
					goto out;
				}
			}	
		}
	}
out:	
	return 0;	
}
