main.c是源代码文件，包含主要业务逻辑。
ops.h是自定义头文件，实现所有的方法。
sqlite3.dll是库文件
sq;ite3.h、sqlite3.c是官方提供的源代码文件和库文件。
sqlite.exe用来操作生成的数据库文件。
less.bat是个文本查看器

int sqlite3_exec(
sqlite3*,
const char *sql,
int (*callback)(void*,int,char**,char**),
void *,
char **errmsg
);
各个参数的意义为：
sqlite3描述的是数据库句柄
sql 要执行的SQL语句
callback回调函数
void *回调函数的第一个参数
errmsg错误信息，如果没有SQL问题则值为NULL
回调函数式一个比较复杂的函数。它的原型是这样的:
int callback(void *params,int column_size,char **column_value,char **column_name){
每一个参数意义如下：
params是sqlite3_exec传入的第四个参数
column_size是结果字段的个数
column_value是返回记录的一位字符数组指针
column_name是结果字段的名称
通常情况下callback在select操作中会使用到，尤其是处理每一行记录数。返回的结果每一行记录都会调用下“回调函数”。 如果回调函数返回了非0，那么sqlite3_exec将返回SQLITE_ABORT，并且之后的回调函数也不会执行，同时未执行的子查询也不会继续执行。
对于更新、删除、插入等不需要回调函数的操作，sqlite3_exec的第三、第四个参数可以传入0或者NULL。
