C++: 冒泡排序Bubble Sort

C++: 冒泡排序

通过指针,数组,函数利用冒泡排序,实现整型数组的升序排列。
原理:
请添加图片描述

#include <iostream>
using namespace std;
void bublesort(int* arr, int len) {
    int i, j, tmp;
    for (i = 0; i < len; i++) {
        for (j = 0; j < len - 1; j++) {
            if (arr[j] > arr[j + 1]) {//相邻比较,如果满足条件则交换
                tmp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = tmp;
            }
        }
    }
}
int main()
{
    int arr[] = { 9,1,5,8,3,7,4,6,2 };
    cout << "排序前顺序:" << endl;
    for (int i = 0; i < 9; i++)cout << arr[i];
    bublesort(arr, 9);
    cout << "\n排序后顺序:" << endl;
    for (int i = 0; i < 9; i++)cout << arr[i];

    system("pause");
    return 0;
}

#include <iostream>
using namespace std;
template<typename T> //整数或浮点数皆可使用,若要使用类(class)或结构体(struct)时必须重载大于(>)运算符

    int i, j;
    for (i = 0; i < len - 1; i++)
        for (j = 0; j < len - 1 - i; j++)
            if (arr[j] > arr[j + 1])
                swap(arr[j], arr[j + 1]);
}

    int len = (int)sizeof(arr) / sizeof(*arr);
    bubble_sort(arr, len);
    for (int i = 0; i < len; i++)
        cout << arr[i] << ' ';

    len = (float)sizeof(arrf) / sizeof(*arrf);
    bubble_sort(arrf, len);

        cout << arrf[i] << ' ' << endl;
    system("pause");
    return 0;
