Help with I/O

I am trying to get a program to write to multiple user selected files. I input the file names as an array of strings, but MVS doesn't let me use the array (or a string for that matter) as a file name. Here is a sample of my problem:

Code:

	vector<string> files(filenum);
	cout<<"Please enter the name of the file(s) you wish to convert"<<endl;
	for (int y=0;y<filenum;y++){
		cin>>files[y];
	}
	for (y=0;y<filenum;y++){
		ofstream openhtml(line);
	}

Sorry if this is a stupid question, but I'm all out of ideas. Thanks!

I've seen wierd stuff with vector in this kind of situation. Perhaps a cast will be necessary?

cin >> (string)files[y];

Let me try it out here. I'll get right back to you

seems to work for me. Maybe you should output the names just to be sure.

cout << files[y].c_str() << endl;

Thanks for your help, but I'm still getting the same error. Maybe if you saw the entire program you would see if I was doing something wrong...

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
 
using namespace std;
 
int main()
{
	ifstream ifs("border.txt");
	string line;
	vector<string> copy(1024);
	int x=0;
	while(getline(ifs,line)) {
	copy[x]=line;
	cout<<copy[x]<<endl;
	x++;
 }
	cout<<"How many files do you want to update the borders for?-->";
	int filenum=0;
	cin>>filenum;
	vector<string> files(filenum);
	cout<<"Please enter the name of the file(s) you wish to convert"<<endl;
	for (int y=0;y<filenum;y++){
		cin>>files[y];
	}
	for (y=0;y<filenum;y++){
		cout << files[y].c_str() << endl;
		ofstream openhtml(line);
	}

	
 return 0;
}

and here is the error message if it helps:

C:\Project Data Files\Tools\onemoretry\mytool.cpp(29) : error C2664: '__thiscall std::basic_ofstream<char,struct std::char_traits<char> >::std::basic_ofstream<char,struct std::char_traits<char> >(const char *,int)' : cannot convert parameter 1 from

No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
Error executing cl.exe.

Thanks again

that error is on the last line in the output loop

ofstream openhtml(line.c_str());

or

ofstream openhtml(files[y].c_str());

will work.

Thanks, it worked great, now I just have to work on getting this program to actually do what I want :-)

Okay, one more question, I'm trying to get the program to open the file, delet everything up untill a certain point , and write the file I've already read in to the top of the new file (it is not a predetermined length, so it must insert, I want to leave the rest of the file intact). I can't seem to figure out how to insert the file with out overwriting. Thanks for all your help, I really appreciate it!

you'll need a third file that you just copy each part into. Then delete and rename where appropriate.

Very good idea, I didn't even think of that. Thanks for all your help.
