Path as argument to c programme

[atmkoh]

I generally use Visual Basic both vb6 and dot net variants. Now I am
using console visual c.
The problem is that I need to get an argument from the user as to the
working directory such as "E:\work\project\data"

In c we have to use "E:\\WORK\\project\\data"

How to I append the extra "\" to the string?

Seasons Greetings and Best regards

OK

Only if it's inside the C program and is the actual string literal. If
it's an argument coming from a file or the command line, we don't have
to double the backslashes.

Where? Try without appending the extra \.

You only need to write extra \ in string literals, because otherwise it's interpreted as an escape character. E.g. "\n" is a string containing a single line-feed character, while "\\n" is a string containing two characters, backslash and 'n'.

In user-entered data, or generally in strings that are generated programmatically, you don't need to double backslashes.
