Thread: open input file twice?

load it into memory

-LC

Your post is about as clear as mud. Maybe this example will help:

Code:

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

int main()
{ 
	ifstream inFile("C:\\TestData\\input.txt");
	string text;
	inFile>>text;
	
	ofstream outFile("C:\\TestData\\output.txt");
	outFile<<text<<endl;

	inFile.seekg(0);//sets the input file pointer to 0
	
	inFile>>text;//reads input file again
	outFile<<text;	

	return 0;
}

i meant load it into memory, character array or what ever and manipulate/play with it there
make a string/array read the file in. Then instead of going through the file again. Go through the string/array as many times as you wish. Parsing/etc.
If you allocated memory remember to free() it err since this is the C++ board... delete it.
std::string would be the best bet.

Or if you don't like dealing with it in memory (for me its usually easier to do in memory or the on just the first run-through) you can use 7stud's pretty good method.
