程序代码：

#include<iostream>
using namespace std;
typedef struct Student
{
    int iScore;
    char cName[20];
    Student():iScore(0)
    {
        memset(cName, '\0', sizeof(cName));
    }
}STUDENT;

int main()
{

    FILE* fp = NULL;
    STUDENT student[10];
    for(int i = 0; i < 10; i++)
    {
        student[i].iScore = rand()%101;
    }
    
    fp = fopen("student.txt", "w+");
    if(fp == NULL)
    {
        printf("file open fail\n");
    }

    for(i = 0; i < 10; i++)
    {
        fprintf(fp,"%d ", student[i].iScore);
    }
    fprintf(fp,"#");
    fclose(fp);

    return 0;
}
