Answer 1

 struct Student
{
    int nYear;
    char czName[20];
    char czNumber[10];
    char czTel[12];
    int nAge;
    float fScore[5];
}Student[10];


int main()
{ 
    int nCount = 0;
    FILE *fp = fopen("22.txt","rb");
    if(fp == NULL)
    { 
        printf("can not open file!\n");
        exit(0);
    }
    for(int i = 0;i < 100;i ++)
    {
        int nRes = fscanf(fp,"%d %s %s %s %d %f %f %f %f %f",&Student[i].nYear,Student[i].czName,Student[i].czNumber,Student[i].czTel,
            &Student[i].nAge,&Student[i].fScore[0],&Student[i].fScore[1],&Student[i].fScore[2],&Student[i].fScore[3],&Student[i].fScore[4]);
        if (nRes == -1)
        {
            nCount = i;
            fclose(fp);
            break;
        }       
    }

    for (int i = 0;i < nCount;i ++)
    {
        printf("%d %s %s %s %d %.2f %.2f %.2f %.2f %.2f\n",Student[i].nYear,Student[i].czName,Student[i].czNumber,Student[i].czTel,
            Student[i].nAge,Student[i].fScore[0],Student[i].fScore[1],Student[i].fScore[2],Student[i].fScore[3],Student[i].fScore[4]);
    }
    fclose(fp);
    return 0;
}
