一个学生的这样搞：

姓名分开，成两个字符串。

分别排序，形成新的字符串，然后输出。

其他学生一样的方法。

#include <stdio.h>
#include <string.h>

#define STU_NAME_MAX_LEN 20
char stu_name[][STU_NAME_MAX_LEN] =
{
    "iker cassilas",
    "luis suarez",
    "cristiano ronaldo",
    "lionl messi"
};

void main()
{
    int stu_count = sizeof(stu_name)/sizeof(stu_name[0]);
    int i, j, k;
    for (i=0; i<stu_count; i++)
    {
        char firstname[STU_NAME_MAX_LEN];
        char familyname[STU_NAME_MAX_LEN];
        int blankpos = 0;

        //将姓名分开
        memset(firstname, 0, STU_NAME_MAX_LEN);
        memset(familyname, 0, STU_NAME_MAX_LEN);
        for (j=0; j<sizeof(stu_name[i]); j++)
        {
            if (stu_name[i][j] == ' ')
            {
                blankpos = j;
                break;
            }
        }
        memcpy(firstname, &stu_name[i][0], blankpos);
        memcpy(familyname, &stu_name[i][blankpos+1], sizeof(stu_name[i])-blankpos-1);
        printf("old: %s %s\n", firstname, familyname);

        //排序
        for (j=0; firstname[j]!='\0'; j++)
        {
            for (k=j+1; firstname[k]!='\0'; k++)
            {
                if (firstname[j] < firstname[k])
                {
                    char ctemp = firstname[j];
                    firstname[j] = firstname[k];
                    firstname[k] = ctemp;
                }
            }
        }
        for (j=0; familyname[j]!='\0'; j++)
        {
            for (k=j+1; familyname[k]!='\0'; k++)
            {
                if (familyname[j] < familyname[k])
                {
                    char ctemp = familyname[j];
                    familyname[j] = familyname[k];
                    familyname[k] = ctemp;
                }
            }
        }
        printf("new:%s %s\n\n", firstname, familyname);
    }
}
