(practice C language every day) pointer sorting problem

Pointer sorting problem

Input 10 Number , Sort the output by absolute value from large to small . Input form ： Input 10 individual float The set of real Numbers Output form ： Keep two significant digits after the decimal point ; The output is arranged from large to small

The following program realizes this function , Please fill in the blanks ：

#include <math.h>
#include <stdio.h>
void paixu(float *p, int n)
{
    int i, j;
    for (i = 0; i < n - 1; i++)
    {
        for (j = 0; j < n - 1 - i; j++)
        {
            if (fabs(p[j]) < fabs(p[j + 1]))
            {
                float tmp;
				tmp = p[j];
                p[j] = p[j + 1];
                p[j + 1] = tmp;
            }
        }
    }
}
int main()
{
    float f[10];
    int i;
    for (i = 0; i < 10; i++)
        scanf("%f", &f[i]);
    paixu(f, 10);
    for (i = 0; i < 10; i++)
        printf("%.2f ", f[i]);
    return 0;
