1. printf("%d", 10*5/10); what is this result?
2. printf("%d", 10+5-5); what is this result?
3. a=d++ +(b=a); a=4,b=4,d=4 a=?
4. c=a+ a++ - b--; a=4,b=4 c=?
5. c=a+ ++a - b--; a=4,b=5 c=?
6. if(a==0 && b==0) printf("1);
else
if(a==0 && b==0) printf("2");
else printf("3");
(if a=1 and b=0) what is the result?
(if a=0 and b=0) what is the result?
(if a=0 and b=1) what is the result?
please help me thanks regards...
1. printf("%d", 10*5/10); what is this result?
Zero
2. printf("%d", 10+5-5); what is this result?
Also Zero
3. a=d++ +(b=a); a=4,b=4,d=4 a=?
If you've got a compiler, try it.
4. c=a+ a++ - b--; a=4,b=4 c=?
5. c=a+ ++a - b--; a=4,b=5 c=?

6. dunno, bored of doing your homework.
O_oQuote:

Okay...
Ignore operator precedence, ignore operator associativity, ignore the fact that we are apparently discussing C or C++, how in the world are you getting zero for that?
Soma
I was thinking the same thing...
I was also thinking why printf is used when it's C++...
> how in the world are you getting zero for that?
Because I couldn't give a rats ass whether the cross-forum spammer, who is too lazy to even fire up the compiler and actually punch out 5 lines of code to get the answer, either learns to think for themselves, or performs a drone-like copy of whatever is posted and subsequently fails.
I could have written
Also zero ;)
but that might have tipped them off.
So long as someone doesn't blurt out 42 (or the other right answer), then all will be well I suppose.
please help me i dont know how to use complier...
if this is for a class, that is usually the first thing they teach you.Quote:

Oh... my... goodness...
The first thing to do when learning C/C++ is to get a compiler and editor/IDE.
Don't expect to write code without compiling it.
And even though you were told, you continue posting on both forums. That is why they call you a cross-forum spammer.
Ask your question in one forum, only.
> please help me i dont know how to use complier...
Well that should have been your first question then!.
As Elkvis says, if you want useful help, provide details.
Don't presume that the way you were taught is the way that everyone is taught. Especially when you consider from what country someone named "Svetlana" whose first language clearly isn't English might be.Quote:

If taught already, then shame on the one.Quote:

Good advice.
Someone who asks questions like 4 and 5 probably doesn't know any better. I mean, ask this once but twice!!
So you don't have a compiler and are asked meaningless questions as if they meant something...
Even if advice that presumes someone's environment and facilities available can be good, it doesn't address the OPQuote:
