Dear Rene,
Sorry, I was out of town, so couldn't reply immediately. I am hereby
sending the datafile and the script file as attachments.
" I have one more question, this is a trivial question may be...
You know we can access files from command line in C++ using argc, argv[]
declarations in the main, likewise, even in C++ or root, how can I read the
file name as a string while running the program. means...
fp = fopen("data.dat","r");
instead of this, I would like to declare
char *ar[];
gets(ar[1]);
fp = fopen(ar[1],"r"); and then access my file.
Can I do this or not?
When I am doing this, its not recognizing the ar[1] value as a file name,
where am I going wrong? Please reply. Thanx
Yours,
Shiva.
