用C语言编写一个程序，内容为职工工资管理系统的设计与实现

就这样吧，工资排序就是比较数的大小，这个会吧？既然只有3个人，就这么简单。如果要查询，就要先保存，写保存函数，再写读取函数，我就不写了。最后建议这种用链表比较好。

printf("请输入职工的信息，\n:");

for(i = 0;i<3;i++)

{

num[i] = i+1;

printf("请输入第%d个信息name:\n",i+1);

scanf("%s",name[i]);

printf("请输入第%d个信息type:\n",i+1);

scanf("%s",type[i]);

printf("请输入第%d个信息money:\n",i+1);

scanf("%f",&money[i]);

}

{

printf("%d %s %s %f",num[i],name[i],type[i],money[i]);

printf("\n");

}

sum+=money[i];

分数太低了。这个不好做啊。
