将dict.txt导入到数据库中（单词一列，意思一列）

#include 
int main(int argc, const char *argv[])
{
	//打开数据库
	sqlite3 *db;
	if(sqlite3_open("./dict.db",&db) != SQLITE_OK)
	{
		fprintf(stderr,"sqlite3_open: %s %d  __%d__\n",\
				sqlite3_errmsg(db),sqlite3_errcode(db),__LINE__);
		return -1;
	}
	printf("sqlite3_open success\n");
	
	//创建表格
	char sql[128]="create table if not exists dict (word char ,mean chars);";
	char* errmsg = NULL; 
	if(sqlite3_exec(db,sql,NULL,NULL,&errmsg) != SQLITE_OK)
	{
		fprintf(stderr,"sqlite3_exec:%s __%d__\n",errmsg,__LINE__);
		return -1;
	}
	printf("create table dict success\n");

	//清空表格
	char arr[128]="delete from dict;";
	if(sqlite3_exec(db,arr,NULL,NULL,&errmsg) != SQLITE_OK)
	{
		fprintf(stderr,"sqlite3_exec:%s __%d__\n",errmsg,__LINE__);
		return -1;
	}
	//打开文件
	FILE *fp=NULL;
	if((fp=fopen("./dict.txt","r"))==NULL)
	{
		perror("fopen error");
		return -1;
	}
	int i=0;
	int flag=0;
	//插入数据
	char buf[128]="";
	char word[64]="";
	char mean[64]="";
	while(fgets(buf,sizeof(buf),fp) !=NULL)
	{
		int len=strlen(buf);
		flag=0;
		for(i=0;i
