C语言用选择法排序，对6个浮点数，这6个浮点数放在数组

下面是使用选择法排序对6个浮点数进行排序的C语言代码：

#include <stdio.h>

void selection_sort(float arr[], int n) {
    int i, j, min_idx;
    for (i = 0; i < n - 1; i++) {
        min_idx = i;
        for (j = i + 1; j < n; j++) {
            if (arr[j] < arr[min_idx]) {
                min_idx = j;
            }
        }
        float temp = arr[min_idx];
        arr[min_idx] = arr[i];
        arr[i] = temp;
    }
}

int main() {
    float arr[6] = {3.2, 1.5, 4.8, 2.7, 6.0, 0.9};
    int n = sizeof(arr) / sizeof(arr[0]);
    printf("Before sorting:\n");
    for (int i = 0; i < n; i++) {
        printf("%.1f ", arr[i]);
    }
    printf("\n");
    selection_sort(arr, n);
    printf("After sorting:\n");
    for (int i = 0; i < n; i++) {
        printf("%.1f ", arr[i]);
    }
    printf("\n");
    return 0;
}

输出结果为：

Before sorting:
3.2 1.5 4.8 2.7 6.0 0.9 
After sorting:
0.9 1.5 2.7 3.2 4.8 6.0
