将十个数从大到小冒泡排序

Question

输入是个数字后输出不了结果，为什么呀？要怎么改才能实现冒泡排序呢？求指导

Answer 1

#include <stdio.h>

int main() {
    int arr[10] = {0};

    for (int i = 0; i < 10; i++) {
        scanf("%d", &arr[i]);
    }

    for (int i = 0; i < 10; i++) {
        for (int j = 0; j < 10 - i - 1; j++) {
            if (arr[j] < arr[j + 1]) {
                int temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }

    for (int i = 0; i < 10; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}
