c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<stdlib.h>

#include<string.h>

struct people

{

    char sex[7];

    float height;

};

int main()

{

    struct people* x;

    int n,i,j=0,k=0,l;

    float a[40], b[40];

    scanf("%d", &n);

    x = (struct people *)malloc(n * sizeof(struct people));

    for (i = 0; i < n; i++)

        scanf("%s %f", x[i].sex, &x[i].height);

    for (i = 0; i < n; i++)

    {

        if (strcmp(x[i].sex, "male") == 0)

        {

            a[j] = x[i].height;

            j++;

        }

        if (strcmp(x[i].sex, "female") == 0)

        {

            b[k] = x[i].height;

            k++;

        }

    }

    for (i = 0; i < j - 1; i++)

    {

        for (l = 0; l < j - i - 1; l++)

        {

            if (a[l] > a[l + 1])

            {

                float temp;

                temp = a[l];

                a[l] = a[l + 1];

                a[l + 1] = temp;

            }

        }

    }

    for (i = 0; i < k - 1; i++)

    {

        for (l = 0; l < k - i - 1; l++)

        {

            if (b[l] < b[l + 1])

            {

                float temp;

                temp = b[l];

                b[l] = b[l + 1];

                b[l + 1] = temp;

            }

        }

    }

    for (i = 0; i < j; i++)

        printf("%.2f ", a[i]);

    for (i = 0; i < k; i++)

        printf("%.2f ", b[i]);

    return 0;
