For example #include&lt;stdio.h&gt; int main() {     for(int i=1; i&lt;=10; ++i)     {         printf(&quot;%d \n&quot;, i);     }     return 0; }  Can the ++i in the for loop updation be i++?
Is there a difference in ++i and i++ in a for loop? Is it simply a syntax thing?
My windows directory is huge How do I do this? I created a user without a home directory and now I want to create one. Not just a folder called new_user, I want the default home directory with all it's folders and hidden files, etc. 3D software like GeoGebra Does it exist a free interactive geometry software, like GeoGebra, which works for 3D geometry? I would be able to draw spheres, great circles, and so on. Cannot favorite once up voted I'm not sure whether this is exactly the same bug as  or whether this is a new bug.  If you up vote a question and then attempt to add it to favorites too you get Question is already favorited:    This also happens if you up vote on the web site and then try to favorite it from Android. If you don't up vote or if you favorite it first and then up vote it appears to work fine. The last two digits of $9^{9^9}$ I tried to calculate the last two digits of $9^{9^9}$ using Euler's Totient theorem, what I got is that it is same as the last two digits of $9^9$.   How do I proceed further? Why did the first Linux developers choose to implement a non-preemptive kernel? Is it to save synchronization?  As far as I know, Linux was developed in the early '90s, when PCs had a single processor. What advantage does a non-preemptive kernel give in such PCs? Why, however, the advantage is reduced by multi-core processors? How to ignore everything in the document environment? I am trying to mount my ext4 (sdc6) partition from a live usb because that's how I deleted two unused partitions left from a prior install of ubuntu, using GParted. The swap is mounted. However, I can't edit fstab, or find anywhere to click in nautilus to mount sdc6. In the terminal, I get the error: "can't find /dev/sdc6 in fstab". I'm afraid to exit the usb and update grub if that partition isn't mounted. Is there any easy way to do this, or do I have to install gksu or some other editor? Or do I need to mount it as sda6?

Is there a way to choose a beginning and ending edge and auto select all the edges in between? I have been using Blender for quite a long time and I just want to make sure that there isn't a better way of selecting edges, that I might not be aware of. It is so cumbersome to have to click every single edge when I don't want to select an entire edge loop but a portion of one instead. I was wondering if there is some way in to specify a start edge and an end edge and then be able to auto select every edge in between?

I notice a weird (well, according to me) thing about passwords. For example, if I type an incorrect password during login, there will be a few seconds' delay before the system tells me so. When I try to sudo with a wrong password I would also have to wait before the shell says "Sorry, try again".  I wonder why it takes so long to "recognize" an incorrect password? This has been seen on several distributions I use (and even OSX), so I think it's not a distribution specific thing. When to use "respectively"? I have been wondering what it means when people use "respectively" in, before, and after sentences. For example:     We are looking for a babysitter to pick up and supervise our kids ages   6 and 3, respectively, on Monday and Friday.   I don't know if this person used it correctly, but if they did what does it mean? If they didn't use it properly what would be the proper usage?  Thanks in advance. Why can my keyboard only digest 6 keypresses at a time? When I slam my hand onto my keyboard, only a maximum of 6 keys will be registered, I've tested this for the past few minutes and was unable to get more than 6. Is this the same on all keyboards? If not, what would be the distinguishing factor, If yes: why 6 specifically?  For clarification: I do not have a usecase for this, I am simply curious Have iPhone 4 with iOS 5.1.1 Trying to update to 6.1.2 (not the latest) via downloaded IPSW but unfortunately getting error:     iphone could not be restored device isn't eligible for the requested   build   After searching for fix all over the internet found some suggestion like putting # in hosts file in line gs.apple.com but not helped.  Have you any idea why I'm getting this error and can't restore iphone? Word for Negatively Surprising I'm searching for a word representing "Negatively surprising", or "Negatively amused" in an appropriate form. Example: Someone who proclaims he aims to do things in the right way has done something in the completely opposite way.    How could you have done such a thing? That action is very ___.   Said with the purpose of showing the contrast between the expected and the actual, and asking for change to adhere with his set goals, instead of just pointing out disappointment.  It is different from  because it asks there about surprise of being affected by the disappointment. The meaning of surprise here is different. How to run a specific program as root without a password prompt? From some comments in the answers for  (now deleted, 10k only), there's confusion around the usage of I vs. me:  While the sentence, "the other attendees are myself and Steve," is agreed to be incorrect, there's confusion about whether the correct form is "the other attendees are me and Steve" or "the other attendees are Steve and I."  (I've always used the heuristic of removing the other people from the sentence, so I always thought "the other attendee is me" would be correct, instead of "the other attendee is I." Is this true, or am I using a flawed heuristic?) Where are Upstart log messages on Ubuntu 13.X? How do I install Python 3.6 using apt-get? This was posted on facebook and people are saying it is incorrect, it should be: "...as you and I"   Which is correct?
