VC++6.0可以运行的程序如何在VS2008上运行

我在VC++6.0写的词法分析程序可以运行，但是不知道怎么在VS2008创建项目和文件的类型，初学者，麻烦指点！附上源代码！
#include <stdio.h>
#include <string.h>

char prog[80],token[8];
char ch;
int syn,p,m,n,sum;
char *rwtab[6]={"begin","if","then","while","do","end"};

void scaner();

void main(){
p=0;
printf("\n please input string;\n");
do {
scanf("%c",&ch);
prog[p++] = ch;
}while (ch!='#');
p=0;
do{
scaner();
switch(syn) {
case 11: printf ("(syn,%d)\n",sum); break;
case -1:printf("error!\n");break;
default:printf("(%d,%s)\n",syn,token);
}
}while (syn!=0);
}

void scaner(){
for(n=0;n<8;n++) token[n]=NULL;
ch = prog[p++];
while(ch==' ')
ch = prog[p++];
if(ch>='a'&&ch<='z'){
m = 0;
while((ch>='a'&&ch<='z')||(ch>='0'&&ch<='9')){
token[m++] = ch;
ch = prog[p++];
}
token[m++]='\0';
--p;
syn=10;
for (n=0;n<6;n++)
if(strcmp(token,rwtab[n])==0){
syn = n+1;
break;
}
}
else
if(ch>='0'&&ch<='9'){
while (ch>='0'&&ch<='9'){
sum=sum*10+ch-'0';
ch = prog[p++];
}
--p;
syn=11;
}
else
switch(ch){
case'<':
m=0;token[m++]=ch;
ch = prog[p++];
if(ch=='>'){
syn=21;
token[m++]=ch;
}
else
if (ch=='='){
syn=22;
token[m++]=ch;
}
else{
syn=20;
--p;
}
break;
case'>':
token[m++] = ch;
ch = prog[p++];

break;

break;
case'+':

case'-':

case'*':

case'(':

case'#':
syn=0;token[0]=ch;break;
default:
syn=-1;
}
}
