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 *fun{STU 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; } return t; } outresult(STU a[],FILE *pf) { int i;for (i=0; i＜N; i++)fprintf(pf, "No=%s Mark-%d\n ",a [i] .num, a[i].s);fprintf(pf, "\n\n "); } main ( ) { STU a[N]={{ "A01 ",81},{ "A02 ",89}, { "A03 ",66},{ "A04 ",87},{ "A05 ",77}, { "A06 ",90},{ "A07 ",79},{ "A08 ",61}, { "A09 ",80},{ "Al0 ",71}};STU *pOrder;int i, m;clrscr ();printf ("*****THE RESULT***** \n");outresult (a, stdout);printf ("\nGive the number of the studentswho have better score: ");scanf ("%d", &m);while (m＞10) { printf("lnGive the number of the students who have better score: ");scanf ("%d", %m);pOrder=fun (a,m);printf("***** THE RESULT*****kn");printf("The top :\n");for (i=0; i＜m; i++) printf("%s %d\n",pOrder[i].num,p0rder [i]. s);free (pOrder); }
