使用结构体写一个排行榜

完成代码如下，运行时却总是在输入第三次数据时报错，请问该如何修改

#define MAXTITL 100
#define MAXAUTL 100
#define N 2
#include<iostream>
#include<stdio.h>
#include<string>
using namespace std;

struct Charts
{
    int score;
    char name[20];
}player[N],t;
int main()
{
    int i, j, t;
    Charts st;
    for (i = 0; i < N; i++)
    {
        memset(&st,0, sizeof(st));
        printf("请输入玩家%d得分：", i + 1);
        scanf_s("%d", &st.score);
        for (j = 0 ; j < i; j++)
        {
            if (st.score > player[j].score)
            {
                for (t = i; t > j; t--)
                {
                    player[t] = player[t - 1];
                }
                
            }
            player[j] = st;
            break;
        }
    }
    if (j < 10)
    {
        printf("请输入玩家%d姓名：", i + 1);
        scanf_s("%s", player[j].name);
    }
    fflush(stdin);
    for (i = 0; i < N; i++)
    {
        printf("%s\t", player[i].name);
        printf("%d\n", player[i].score);
    };
    return 0;
};

下午忙，还没来得及搞。你这个数组大小N写死了是2，你咋能输入第三组数据哈

#define MAXTITL 100
#define MAXAUTL 100
#define N 100
#include<iostream>
#include<stdio.h>
#include<string>
using namespace std;
struct Charts
{
    int score;
    char name[20];
}player[N], t;
int n = 0;
int main()
{
    int i, j, t;
    struct Charts st;
    printf("请输入玩家数量:");
    scanf_s("%d", &n);
    for (i = 0; i < n; i++)
    {
        memset(&st, 0, sizeof(st));
        printf("请输入玩家%d得分：", i + 1);
        scanf_s("%d", &st.score);
        for (j = 0; j < i; j++)
        {
            if (st.score > player[j].score)
            {
                for (t = i; t > j; t--)
                {
                    player[t] = player[t - 1];
                }
                player[j] = st;
                break;
            }
        }
        if (j < 10)
        {
            printf("请输入玩家%d姓名：", i + 1);
            player[j] = st;
            scanf_s("%s", player[j].name,20);
        }
    }

    for (i = 0; i < n; i++)
    {
        printf("%s\t", player[i].name);
        printf("%d\n", player[i].score);
    };
    system("pause");
    return 0;
};

在第三次输入语句前加个getchar(),吃掉上面的回车('\n')字符
