Checking to see if the input has all of the compare line

[drdroid]

Here's the source, how can I use the same functions and everything to check for the entire line of the compare instead of just one word. Also, how can I get it to have one word files... This is getting really crapped up.

-This is where the string search problem is, I don't know what's wrong with the crapped up part, I think their all involved.

void cortana::find_line()
{
	linenumber=0;
	ifstream check_in("compare.txt");
	while(linenumber!=40)
	{
		getline(check_in,str,'\n');
		str=lower(str);
		if(strstr(str.c_str(),input.c_str()))
		{
			line=linenumber;
			prep=true;
			cortana::find_responce();
			break;
		}
		else if(str=="")
		{
			prep=false;
			cortana::find_responce();
			break;
		}
		else if(input!=str)
		{
			linenumber++;
		}
	}
	check_in.close();
}

void cortana::find_responce()
{
	cout << line;
	getch();
	linenumber=0;
	ifstream check_out("responce.txt");
	if(prep==true)
	{
		while(linenumber!=line+1)
		{
			getline(check_out,str,'\n');
			if(linenumber==line)
			{
				responce=str;
				break;
			}
			else
			{
				linenumber++;
			}
		}
	}
	else if(prep==false)
	{
		responce="I don't understand.";
	}
	check_out.close();
}

Shouldn't you reverse the order of the arguments to strstr()?

strstr( text , textToSearchFor )

but now i don't get multi-word answers.
