int main() {

	cout << "请选择副本难度" << endl;
	cout << "1、普通" << endl;
	cout << "2、中等" << endl;
	cout << "3、困难" << endl;

	int select = 0;
	cin >> select;

	switch (select)
	{
	case 1:
		cout << "您选择的是普通难度" << endl;
		break;
	case 2:
		cout << "您选择的是中等难度" << endl;
		break;
	case 3:
		cout << "您选择的是困难难度" << endl;
		break;
	default:
		break;
	}
	system("pause");
	return 0;
}

	for (int i = 0; i < 10; i++)
	{
		if (i == 5) {
			break;
		}
		cout << i << endl;
	}
	system("pause");
	return 0;
}

			if (j == 5) {
				break;
			}
			cout << "* ";
		}
		cout << endl;
	}
	system("pause");
	return 0;
}

continue 语句

如果是奇数输出，偶数不输出

cpp 复制代码

#include <iostream>
using namespace std;


int main() {

	for (int i = 0; i <= 100; i++)
	{
		if (i % 2 == 0) {
			continue;
		}
		cout << i << endl;

	}

	system("pause");
	return 0;
}

goto语句

cpp 复制代码

#include <iostream>
using namespace std;


int main() {

	cout << "1、xxxxx" << endl;
	cout << "2、xxxxx" << endl;
	goto FLAG;
	cout << "3、xxxxx" << endl;
	FLAG:
	cout << "4、xxxxx" << endl;
	cout << "5、xxxxx" << endl;


	system("pause");
	return 0;
}
