学生记录由学号和成绩组成,N名学生的数据已放入主函数中的结构体数组中,请编写函数fun,其功能是:把分数最低的学生数据放入b所指的数组中。注意:分数最低的学生可能不止一个,函数返回分数最低的学生人数。 注意:部分源程序在文件PROG1.C中。 请勿改动主函数main和其他函数中的任何内容,仅在函数fun的花括号中填入你编写的若干语句。 #include <stdio.h> #deftne N 16 typedef struct {char num[10]; int s; }STREC; mt fun( STREC * a, STREC * b ) { } main( ) { STREC s[N] = {{"GA05" ,85 }, {"GA03" ,76}, {"GA02",69}, {"GA04",85}, {"GA01",91},{"GA07",72},{"GA08",64},{"GA06",87}, {"GA015",85}, {"GA013",91},{"GA012",64}, {" GA014",91/, {"GA011",91}, {"GA017",64},{"GA018",64},{"GA016",72t}}; STREC h[N]; int i,n; FILE * out; n=fun(s,h); printf("The % d lowest score :\n",n); for(i=0;i<n; i+ +) printf("% s %4d\n", h[i]. num,h[i].s); printf(" \n"); out=fopen("out.dat","w"); fprintf(out,"% d\n",n); for(i=0;i<n;i+ +) fprintf(out,"%4d\n",h[i].s); fclose (out); }
