Non-Working Code

Hi Gurus,

I'm not able to get this code to work. Can any one help please?

Code:

#include <fstream>
#include <iostream>
#include <string>
using namespace std;

int main()
{
	string c,d = "";
	fstream reads;
	reads.open("R0_1st.txt",ios ::in);
	fstream writes;
	writes.open("new.txt",ios::in|ios::out);
	reads.unsetf(ios::skipws);
	
	while ( getline ( reads, c ) ) {
		cout<<c<<endl;
		if ( c.find ( "Adiabatic Efficiency" ) != string::npos )
			
		{	 
			cout<<">>>>>>>>>>>>>>>"<<endl; //Just to make sure it got here
			while( getline (writes,d) )
			{
				if ( d.find ("replace here") != string::npos )
				{
					cout<<"<<<<<<<<<<<<<<<"<<endl; //Just to make sure it got here
					writes<<c;
				}
			}
		}
	}

	return 0;
}

The textfile returns nothing. Does anyone know where I am going wrong?

Thanks,

Sheilah

You might want to check to see if the files opened successfully.

Code:

	reads.open("R0_1st.txt",ios ::in);
	if (!reads.is_open())
	{
		cout << "Unable to open R0_1st.txt" << endl;
		return 1;
	}

	fstream writes;
	writes.open("new.txt",ios::in|ios::out);
	if (!writes.is_open())
	{
		cout << "Unable to open new.txt" << endl;
		return 2;
	}

And I'm glad someone deleted Cool-August's post.

Actually, I did that after realizing how stupid it was.

LOL

Thanks for the idea. And thanks for being nice about it

Well there's the utterly inept approach of copying someone elses work which springs to mind.
string search and copy in a file !

Amazing, they must be in the same class.

Sheilah, why did you try to compile script that you already knew didn't work?

Hello SheilahT,

Just make sure you have a '\n' at the end of that "new.txt" if you donnot have one there, the put pointer will be placed at the end of the file so that you will not be able to write at that position.

Hope that helps.

Regards.

Working together.

Sorry
