Getting Filename
Hi all,
Iam outputting Data into an ofstream file.
The path & filename of the output file is given in the program argument.
So In main() Function in main.cpp,I will get the filename,But Iam opening my output file in some other file(x.cpp) & I want to create the output file in this file only .I dont want pass the filename through functions().
Is there any other way to get the "File name " in x.cpp?
Thanks in advance..

In main, you could save the arguments in a global variable or stuff it away in some static class initialization.
-
If IAM Declaring it as a global variable in main.cpp,How will I access it in my x.cpp.I dont want to give a main.h in my x.cpp file.
-
To access a variable in ONE module even though the variable is
defined in another, as long as the modules are linked, you can
use the extern keyword.
In main.cpp:
In x.cpp:
Code:
extern int g_variable;
