用C语言将文本基本转换为结构程序。为什么我总是得到奇怪的输出？

这是我的程序，你可以忽略主要部分：

#include<stdio.h>
#include<string.h>

typedef struct{
    char firstname[20];
    char lastname[20];
    int assignments[5];
    int labs[5];
    int midterm;
    int finalM;
}myclass;

myclass gng1105[10];
void update();
void printList();
void addStudent();
int main(){
    int option;
    update();
    while(option!= 3){
    printf("Please enter the option number:\n1.View the information for a specific    student\n2.add a student number\n3.Exist\n");
    scanf("%d", &option);
    if(option == 1){
        printList();
    }
    else if (option == 2){
    addStudent();
    }
    else if (option == 3){
        printf("system closed");
        break;
    }
    else{
         printf("invalid input");
    }

   printf("******************************************************************************\n");
    }
    return 0;
 }

void update(){
     FILE *fp;
    fp = fopen("myclass.txt", "r");
    int i = 0;
    if (fp == NULL)
        printf("Error opening file\n");
     else{
      while(!feof(fp)){
      fscanf(fp,"%s%s%d%d%d%d%d%d%d%d%d%d%d%d", gng1105[i].firstname, 
                                                gng1105[i].lastname,
                                                &gng1105[i].assignments[0],
                                                &gng1105[i].assignments[1],
                                                &gng1105[i].assignments[2],

                                                &gng1105[i].midterm,
                                                &gng1105[i].finalM);
      i++;

      }
    }
    fclose(fp);

}

void printList(){
    int i;
    for(i = 0;i <10 ; i++){
        printf("%s %s %d %d %d %d %d %d %d %d %d %d %d %d", gng1105[i].firstname,
                                                            gng1105[i].lastname,
                                                            gng1105[i].assignments[0],
                                                            gng1105[i].assignments[1],

                                                            gng1105[i].assignments[3],
                                                            gng1105[i].assignments[4],
                                                            gng1105[i].labs[0],
                                                            gng1105[i].labs[1],
                                                            gng1105[i].labs[2],

    }

}


void   addStudent(){
}

这是输出，看起来很奇怪，甚至错误看起来不一致（无法发布图像抱歉）：

如果有人能帮助我，我将不胜感激

看起来您在

结构中忘记了
studentId
字段。您正在将学生ID号（例如100001）分配给
gng1105[i]。作业[0]

您的
struct
的定义如下：

typedef struct
{
    char firstname[20];
    char lastname[20];
    int studentId; // <<<------ This is missing
    int assignments[5];
    int labs[5];
    int midterm;
    int finalM;
} myclass;

typedef结构
{
charfirstname[20]；
char lastname[20]；
int studentId；//您可能要做的第一件事是在
printf（）的末尾添加
\n
格式化字符串，这样你的输出就可以被分成每条记录一行。这会有很大帮助。@user3064115你能发布新的输出吗？这是我的错误，现在好了……非常感谢！我现在感觉很傻……在这个愚蠢的小错误上花了一个小时。@user3064115有时你只需要另一双眼睛。很高兴我能帮上忙P
