c/c++语言开发共享使用fscanf（）读取多个值（如下面的文本文件中所示）

新来的fscanf（）… plz帮助

程序

#include typedef struct { int rollnum; char name[30]; int mark1; int mark2; int mark3; }data; int main(int argc,char* argv[]) { int total,c1,c2,i; char str[30]; FILE *original,*pass,*fail; data *student; original=fopen("C:\Users\user\Desktop\struct.txt","r"); pass=fopen("C:\Users\user\Desktop\pass.txt","w"); fail=fopen("C:\Users\user\Desktop\fail.txt","w"); for(i=0;irollnum, (student+i)->name, &(student+i)->mark1, &(student+i)->mark2, &(student+i)->mark3); total=student[i].mark1+student[i].mark2+student[i].mark3; if(total>50) fprintf(pass,"%d. %s %dn",c1,student[i].name,total); else fprintf(fail,"%d. %s %dn",c2,student[i].name,total); c1++,c2++; } printf("Successfuln"); fclose(original); fclose(pass); fclose(fail); return 0; } **struct.txt** 1 blesswin 20 40 50 2 sam 40 10 20 3 john 50 20 60 4 james 50 40 70 5 peter 10 40 80 

该计划是根据他们的总数将学生分组为两个文件…我似乎有一些问题，但fscanffunction…你的帮助，感谢…提前感谢

 data *students; students = malloc(number_of_students * sizeof(*students)); if (students==NULL) printf("Error: failed to allocate memoryn"); 

 for(i=0;i 

 free(students);
