fscanf(fp,"%s,%d,%f,%f,%f,%f",stu[i].name,&stu[i].num,&stu[i].chinese,&stu[i].english,&stu[i].math,&stu[i].average);讀取時候都要用%s,不然你讀取的就有問題，如果想拿字符串轉變成int 可以使用atoi 例如：char num="456";int a=atoi(num)a就是456了atof(將字符串轉換成浮點型數)atoi(將字符串轉換成整型數)atol(將字符串轉換成長整型數)strtod(將字符串轉換成浮點數)改為：后面的變量自己，轉換之后重新給結構體賦值fscanf(fp,"%s,%s,%s,%s,%s,%s\n",stu[i].name,&stu[i].num,&stu[i].chinese,&stu[i].english,&stu[i].math,&stu[i].average);
