Stack around the variable 'head_path' was corrupted

这是一头文件，查询数据

void Select()

    int year,mon, day, hour, min;//定义要查询的时间

    char head_path[70] = "D:\\zuoye\\lzh2020031070\\lzh2020031070\\data";//文件上级目录的路径
    char file_path[70];//文件路径名字,注意不要堆栈使数组越界
    char time_date[70];//准确时间
    int flag = 0;//文件存在标志,1为存在，0为不存在
    char line_date[1024];//查找每行的数据
    int tmper;//定义温度
    char str_temper[6];
    char show_temper[6];//显示的温度格式
    int j;


    printf("请输入要查询DMGD数据的年月日时分:（eg:2015-01-01 00:03）");

            exit(0);
        }
        while(fgets(line_date,1024,fp) != NULL)//将每行数据写入line_date
        {

            {

        /*---------处理温度的格式-----------*/

        {
            str_temper[0] = '0';
            str_temper[1] = '.';
            str_temper[2] = str_temper[4];
            str_temper[3] = '\0';
        }
        for (j = 0; str_temper[j] != '\0'; j++)
        {
            if (str_temper[j] == ' ')//当温度不是4位时
            {

                    show_temper[i] = str_temper[j];
                }
            }
            else
            {
                strcpy(show_temper,str_temper);
            }
        }

    }

    /*------显示---------------*/
    if(flag == 1)
    {
        printf("\n查询到温度是%s℃", show_temper);
    }
    else
    {
        printf("\n要查询的数据缺失");
    }
    printf("\n自动站数据查询完毕");
    system("pause");
}

在运行的时候，显示堆栈了，但增加了line_data和head_path的值，还是会有错误
