Here is the solution in details:
There is a discrepancy with the actual function and the header file. That's Microsoft's mistake which due to be fixed.
- Go to MAPIUtil.h where OpenStreamOnFile is declared. Change
__in LPCTSTR lpszFileName,
to
__in_opt LPCSTR lpszPrefix,
- Use ASCII file name when calling OpenStreamOnFile

Yes, use standard MS Chart control.
Never use external libs (Win32 api has all)

Hi,
I was asked the below in an interview:-
What does the following code below do?
<br />
char nextChar();<br />
<br />
int main()<br />
{ <br />
char ch;<br />
ch = nextChar() != '\0';<br />
std::cout << (int) ch;<br />
<br />
return 0;<br />
}<br />
I said it would not compile since there is no definition (only a declaration) of the function nextChar() but the answer was 0 or 1. I am not sure why and also how can you use the != operator outside a if or while statement (i.e. something that expects true or false ?
Thank you for any input.

This part of the code actually "returns" something (true or false). You then assign the result of the comparison into the ch variable. true is usually 1 and false is 0. So, your character will contain either 0 or 1. If you try to ouptut as it is (so, without the casting to an integer), you will end up printing the character whose value is 0 or 1 (so, not printable character), that's why you need to cast it to an integer.
I guess that having a body for your function was not really important for the interview question: they simply have a function that returns a character...

Hi ya,
Thanks for your reply. Yes as you correctly said the answer is 0 or 1. I got confused because of the lack of function definition.
Can I ask how it is possible that you can use the != operator without being enclosed in a statement that expects true / false ? e.g. while() , if()
Thanks for any information.

!= is a binary operator that may be used in any expression.

Yes you should get a linker error, due to the missing function definition
You need to google first, if you have "It's urgent please" mentioned in your question.

Most interview questions just use code fragments, and you're supposed to assume functions exist in other libraries (that's generally spelled out in the interview).
Mind you, this is a very simple example question and probably meant as a warm up, not actually a real test. You should see the kinds of questions we ask in our interviews (although coding tests are only a small part of them).
There are three kinds of people in the world - those who can count and those who can't...

Hi ya,
Thanks for your post, was wondering if you could put up some of your interview code questions?
|

LOL - I wouldn't be allowed to do that, just in case anyone reading here comes in for an interview (which is quite possible)

Your point is correct (please note, however, that you would get a linker error, not a compiler one).
Now suppose nextChar is defined, somewhere (it's actual implementation doesn't matter).
minkowski wrote: but the answer was 0 or 1. I am not sure why and also how can you use the != operator outside a if or while statement (i.e. something that expects true or false ?
nextChar() != '\0';
the above expression evaluates true whenever nextChar return a value different from '\0', false otherwise. Since true is 1 [^] (false is 0) an implicit cast from bool to char (that is an integer type) happens and you get ch=1 (or ch=0).
BTW Are you that Minkowski [^]?

shhhh. dont' tell anyone, but i'm letting it leak out - a triangle... has 3 sides. shhh. don't let anyone know though

That's the reason geometry is soooo difficult to grasp: triangle => three sides...while plain common sense would suggest triangle => three angles, or, at least, triside => three sides.

so it should be a quad - right - angle for a rectangle ?

This is what the question is aiming at.
It's a matter of operator precedence.

Dear Sir (or Madam), you're supposed to be a software developer.
Software developers are supposed to develop code.
At least developers are supposed to read forum guidelines [^] before posting here.
