一、N-S流程图;

二、运算原理说明;

1、排序前数据;

a[10] = { 34, 67, 90, 43, 124, 87, 65, 99, 132, 26 };

2、运算过程;

i = 0; j < 9;

j = 0;

34 > 67(不成立,不执行转换), 90, 43, 124, 87, 65, 99, 132, 26;

j = 1;

34, 67 > 90(不成立,不执行转换), 43, 124, 87, 65, 99, 132, 26;

j = 2;

34, 67, 90 > 43(成立,交换位置), 124, 87, 65, 99, 132, 26;

34, 67, 43, 90, 124, 87, 65, 99, 132, 26;

j = 3;

34, 67, 43, 90 > 124(不成立,不执行转换), 87, 65, 99, 132, 26;

j = 4;

34, 67, 43, 90, 124 > 87(成立,交换位置), 65, 99, 132, 26;

34, 67, 43, 90, 87, 124, 65, 99, 132, 26;

3、排序运算后;

a[10] = { 34, 26, 43, 65, 67,  87, 90, 99, 124, 132 };

三、运行结果;

四、源代码;

# define _CRT_SECURE_NO_WARNINGS
# include <stdio.h>

int main()
{
	//初始化变量值;
	int a[10] = { 0 };
	int i = 0;
	int j = 0;
	int t = 0;

	//提示用户;
	printf("请输入10个数值:");

	//循环获取数值;
	for (i = 0; i < 10; i++)
	{
		//获取;
		scanf("%d", &a[i]);
	}

	//换行;
	printf("\n");

	//循环冒泡排序;
	for (i = 0; i < 9; i++)
	{
		//冒泡排序;
		for (j = 0; j < 9 - i; j++)
		{
			//判断;
			if (a[j] > a[j + 1])
			{
				//交换;
				t = a[j];
				a[j] = a[j + 1];
				a[j + 1] = t;
			}
		}
	}

	//提示用户;
	printf("10个数按从小到大的顺序输出结果为:");

	//输出;
	for (i = 0; i < 10; i++)
	{
		//打印;
		printf("%d ", a[i]);
	}

	return 0;
