Anyone can tell me the different between this.....in programming c?
i++ and ++i
Anyone can tell me the different between this.....in programming c
Test it.
Gives...Code:#include <stdio.h> #include <stdlib.h> int main(void) { int i; int r; // test #1 i = 7; r = ++i * 10; printf("%d %d \n",i,r); // test #2 i = 7; r = i++ * 10; printf("%d %d \n",i,r); return 0; }

8 70
Why two different answers?
++i increments i before the calculation
i++ increments i after the calculation
And, you wouldn't believe how many times I've tripped over this in various programs.

thank!!!
Anyone can solve this for me ....
n=2
n*=((3*4)/2)-9);
We cannot. What do you think it produces, and why?

As for solving it - what fun would that be? Write a little program to solve it.
Big silly you!
i dont want in CODING .... if anyone can solve it in math and tell what it answer?
It is BASIC math, part of general education!
Don't tell me you don't know how to multiply, add and subtract?
i know but i want to make sure the answer same with other people answer...can anyone answer this:
n=2
n*=((3*4)/2)-9);
in math
Then post your answer to show that you actually have done it.
Otherwise people will think you're just looking for an answer.
And why not run it in a compiler and check the output?
the answer is
n = -6
Instead of reducing members of this community into pocket calculators, you could actually use a pocket calculator to double check. That said, this is the kind of thing that proves that you are not smarter than a fifth grader if you cannot compute it mentally.
That is correct. But are you sure that I am telling the truth? Really, what is stopping you from using a pocket calculator, or even just taking a pen and paper and working it out step by step? If you cannot trust yourself on something so simple when you work it out meticulously, you're doomed.
Look up a C++ Reference and learn How To Ask Questions The Smart Way
Assuming n is a signed integer, I get the same answer.
so you answer is -6
