Thread: A strange problem with creating a file

I have been working on this program for some time now, and i've stripped it down into smaller executables so i can test each individual part of my code (a lot of debugging to do)...anyhow, i have a part of it worked out finally, it works, sort of. It is supposed to create a file name logically by concatenating two c style strings...that all works, but the final output it strange...code like this:

Code:

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

char id[5];
char fileHandle[]=".xml";
char* fileName;


int main() {


cout<<"enter id"<<endl;
cin>>id;

fileName=strcat(id,fileHandle);
//now open the file and create the fout object for writing
ofstream fout(fileName);
fout<<"ok";
fout.close();


return 0;
}

when i run the program, it creates a file with the correct data in it, however the file extension is messed up, the last letter of the file extension (in this case being 'L') is replaces with '1/4A' i've tried with different file extensions and the same thing happens....does anyone know whats happening here? i thought perhaps it has something to do with the terminating character of the string...but i don't know. thanks

well thanks anyway, i tried it but it didn't work....this time the file was called .xm@1/2A ...very strange, all the source code was the same besides adding the size 100 to the c string fileHandle....

oh sorry, i feel stupid...anyhow i see why you make id so big, thanks for the help.
