Hi guys I came across one question How can I write scanf("%ld" &n)
which is in C into C++ language.

Aside from that, scanf is one of the functions that also exist in C++ (in the header cstdio instead of stdio.h), but you should use iostreams instead (introduction at the link fire posted).

PS: I know you used iostreams earlier... is it just that you wanted to know what scanf does or what?

No I mean this %ld what does it mean in C. And how can I write it in C++

[hanst99]

%ld means long decimal integer, which is a long int in C++ (in C too by the way). It's the scanning format scanf uses to retrieve input, and you don't need that in c++ cause you got iostreams.

Thanks hanst99 I understood, :)

Use iostream if you want your exe to be 450kb bigger :) (and even if do NOT USE it, by simple inclusion of <iostream> header the executable size grow that much).

modoran, then your compiler sucks or you are simply to incompetent to let your compiler strip debugging information. Sad but true.
