下列给定程序中,函数fun()的功能是:对N名学生的学习成绩,按从高到低的顺序找出前叫m≤10)名学生来,并将这些学生数据存放在一个动态分配的连续存储区中,此存储区的首地址作为函数值返回。 请改正程序中的错误,使它能得出正确的结果。 注意:不要改动main函数,不得增行或删行,也不得更改程序的结构. 试题程序: #include <conio.h> #include <string.h> #include <stdio.h> #include <alloc.h> #define N 10 typedef struct ss char num[10]; int s; STU; STU *funSTU a[], int m) STU b[N] ,*t; int i, j,k; /*************found**************/ *t=calloc (m, slzeof (STU)); for(i=0;i<N;i++) b[i]=a[i]; for(k=0; k<m; k++) for (i=j=0;i<N;i++) if (b[i].s>b[j].s) j=i; /*************found**************/ t[k].num=b [j].num; t[k].s=b[j] s; b[j].s=0;
