[数据结构与算法]C++——循环结构

1、循环结构-while语句

#include<iostream>
using namespace std;

int main()
{

	//while循环
	//在屏幕中打印0 ~ 9 这10个数字
	//int num = 0;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	//num++;
	//cout << num << endl;

	int num = 0;

	//while（）中填入循环条件
	//注意事项：在写循环一定要避免死循环的出现
	while (num < 10)
	{
		cout << num << endl;
		num++;
	}

	system("pause");

	return 0;
}
