急~~~~求c语言翻译程序用文件处理的方法~~~~高分送上

Question

#include <stdio.h>
#include <string.h>
void main()
{
void find();

printf("\t输入你要查询的关键字，bye是结束\n");

find();
}

void find()
{
char *p,w[50];
p=w;
int i=0;
while(1)
{
scanf("%s",p);
if (strcmp(p,"bye")==0)
{
i=1;
printf("\t\t\t\t88\n");
break;

}

if (strcmp(p,"[code]auto")==0)
{i=1; printf("自动变量\n");}
if (strcmp(p,"double")==0)
{i=1; printf("双精度变量\n");}
if (strcmp(p,"int")==0)
{i=1; printf("整型变量\n");}

{{{这里还有很多，老师不给我用if处理，求教，紧急！！！！}}}

if(i==0)
printf("错了，重新输啊\n");
}

}

就是这个程序，把那些对int,float的翻译部分用文件来处理，拜谢
紧急啊
