程序通过定义学生结构体数组,存储若干名学生的学号、姓名和三门课的成绩。函数fun的功能是:将存放学生数据的结构体数组,按姓名的字典序(从小到大)排序。#include #include struct student { long sno; char name[10]; float score[3]; }; void fun(struct student a[], int n) { struct student t; int i, j; /**********found**********/ for (i=0; i 0) { t = a[i]; a[i] = a[j]; a[j] = t; } } main() { struct student s[4]={{10001,"ZhangSan", 95, 80, 88},{10002,"LiSi", 85, 70, 78}, {10003,"CaoKai", 75, 60, 88}, {10004,"FangFang", 90, 82, 87}}; int i, j; printf("\n\nThe original data :\n\n"); for (j=0; j<4; j++) { printf("\nNo: %ld Name: %-8s Scores: ",s[j].sno, s[j].name); for (i=0; i<3; i++) printf("%6.2f ", s[j].score[i]); printf("\n"); } fun(s, 4); printf("\n\nThe data after sorting :\n\n"); for (j=0; j<4; j++) { printf("\nNo: %ld Name: %-8s Scores: ",s[j].sno, s[j].name); for (i=0; i<3; i++) printf("%6.2f ", s[j].score[i]); printf("\n"); } } A. n B. n+1 C. a(i) D. n-1
