人员的记录由编号和出生年、月、日组成,N名人员的数据已在主函数中存入结构体数组std中,且编号唯一。函数fun的功能是:找出指定编号人员的数据,作为函数值返回,由主函数输出,若指定编号不存在,返回数据中的编号为空串。 #include #include struct student { long sno; char name[10]; float score[3]; }; void fun(struct student a[], int n) { std[i].num t; int i, j; /**********found**********/ for (i=0; i for (j=i+1; j if (strcmp( std[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"); } }
