I kept getting the error "Command terminated by signal 11" when I try to save a string into an array of strings. After changing the code from the link below, now the name prints out ���W.   I used this  to fix my code off of but it is still causing me to get the error "Command terminated by signal 11".       #include&lt;stdio.h&gt;     #include&lt;string.h&gt;      void getName(char* c[], int size);     int main(void) {         int yenoSize = 0;         int strSize = 0;     char name1[30];     char* name[30];     char* students[5][30];      for(int i=0;i&lt;1;i++){     getName(name, strSize);     students[i][0] = name1;     }      for(int k=0; k&lt;1;k++){     printf("Student Name: %s \n", students[k][30]);      }      }      void getName(char* c[], int size){     char name1[30];     printf("Enter student name: ");     fgets(name1, 30, stdin);     c[0] = &amp;name1[0];     printf("%s", name1);      }   The output is supposed to print out the name that the user inputs (Student Name: Jon) but it is currently printing ���W. How can I fix the problem? I believe the problem exists with the name pointer pointing to null. Is that the problem? I appreciate the help!
As a follow-up to :  From what I've seen, this should work as expected:  void greet(){   char c[] = "Hello";   greetWith(c);   return; }   but this will cause undefined behavior:  char *greet(){    char c[] = "Hello";   return c; }   If I'm right, what's the best way to fix the second greet function? In an embedded environment? On a desktop?
I am looking for shapefiles or a list of suburb names for Melbourne and Canberra. I have ABS shapefiles, but I need to filter that to end up with only metropolitan suburbs.  My shapefile has codes in it for  - I just need to know which suburbs belong to the metros. What is the difference between fastboot oem unlock and fastboot oem unlock-go? I'm having issues unlocking my Nexus 7 2013 WiFi's bootloader, and it was suggested that I try fastboot oem unlock-go instead of fastboot oem unlock. Both seem to act the same on my device, however both also fail on my device so it is possible that the difference appears after the failure on my end comes. Regardless, I would like to know: What is the difference between these two commands? I'm not managing to find documentation. Is the humanoid appearance of most alien species in the Star Trek universe ever canonically addressed? The vast majority of intelligent species in the Star Trek universe are bipedal, humanoid creatures.  From the lot I've seen of TOS, TNG, DS9, Voyager, Enterprise, and the movies, it seems that this coincidence goes largely unquestioned.  Metaknowledge grants that it is much easier to have human actors portray human-like beings, and so this was probably done due to budgetary/technological limitations.  However, I'm wondering if an in-universe reason for this was ever given or explored? How do I install a different Python version using apt-get? Limit point versus limit and implications for convergence I understand that similar questions to this have been asked  and  but I believe my question is different because with regards to (1) I am not asking about the set $X$ that contains the points of my sequence and with regard to (2) because I have the distinct definitions of limit and limit point in mind. That said:  My Question: My textbook, Fundamental Ideas of Analysis by Michael Reed, defines a limit point as:     Definition: Let $(a_n)$ be a sequence of real numbers. A number $d$ is called a limit point if, given $\epsilon &gt; 0$ and an integer $N$, there exists $\color{red}{\mathrm{ an }} \ n \ge N$ so that $|a_n - d| \le \epsilon$.    The definition of a limit is as follows:     Definition: We say that a sequence $(a_n)$ converges to a limit $a$ if, for every $\epsilon \ge 0$, there is an integer $N(\epsilon)$ so that $|a_n - a| \le \epsilon \color{red}{\text{  for all  }} n \ge N$.    From these definitions, and given this question:     If a sequence converges it has exactly one limit point. Is the converse true? If not, provide a counterexample   Can I conclude that the converse is indeed true simply by appealing to the definitions, or do I need a tighter proof. And if I do, I'm a little stuck on how to refine this proof. Chat is down. Where can I find when it'll be back up? Where does $PATH get set in OS X 10.6 Snow Leopard? I type echo $PATH on the command line and get  /opt/local/bin:/opt/local/sbin:/Users/andrew/bin:/usr/local/bin:/usr/local/mysql/bin:/usr/local/pear/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin  I'm wondering where this is getting set since my .bash_login file is empty.  I'm particularly concerned that, after installing MacPorts, it installed a bunch of junk in /opt. I don't think that directory even exists in a normal Mac OS X install.  Update: Thanks to  for correcting my echo $PATH statement I have this  problem with Ubuntu 16.04 LTS. All programs and all menus have black boarders and Terminal is displayed black:    The problem appeared after installing  tool and installing all Kali Tools. ［I'm Done］ button is available after ［Save Edits］ even when nothing was edited in First Posts queue What is a good criterion or rule-of-thumb for determining when a control should be greyed-out and when should it be completely invisible? In doing instanton problems or when connecting quantum field theory to statistical mechanics, I often see people trying the Wick rotation trick by defining an imaginary time $\tau\equiv it$. So, in this case, we should make sure that $\tau$ is imaginary, right? However, I often see places where people seem to handle $\tau$ as a real number, for example setting $\tau$ to $\pm\infty$. Moreover, I remember in one of my quantum mechanics classes, the professor said the Euclidean time $\tau$ was real. I am so confused and need some good explanations.

How to do a generalized linear model with multiple dependent variables in R? Given that   $x^x = y$; and  given some value for $y$   is there a way to expressly solve that equation for $x$? I have a problem called "The Prison Problem" that I need to explain to my 9-year-old cousin. I would think that he has just started learning about divisors and perfect squares, and as such, I have a proposed solution. Any input from you guys would be welcome, as to what is the best way to go about this.  Problem:  There was a jail with 100 cells in it, all in a long row. The warden was feeling very jolly one night and told his assistant that he wanted to give all the prisoners a wonderful surprise. While they were sleeping, he wanted the assistant to unlock all the cells. This should be done, he told the assistant, by putting the key in each lock, turning it once. The assistant did this, then came back to report that the job was done. Meanwhile, however, the warden has second thoughts. "Maybe I shouldn't let all the prisoners free," he said. "Go back and leave the first cell open, but lock the second one (by putting the key in and turning it once). Then leave the third open, but lock the fourth, and continue in this way for the entire row." The assistant wasn't very surprised at this request as the warden often changed his mind. After finishing this task, the assistant returned, and again the warden had other thoughts. "Here's what I really want you to do," he said. "Go back down the row. Leave the first two cells as they are, and put your key in the third cell and turn it once. Then leave the fourth and fifth cells and turn the key in the sixth. Continue down the row this way." The assistant again did as instructed. Fortunately, the prisoners were still asleep. As a matter of fact, the assistant was getting pretty sleepy, but there was no chance for rest yet. The warden changed his mind again, and the assistant had to go back again and turn the lock in the fourth cell and in every fourth cell down the row. This continued all through the night, next turning the lock in every fifth cell, and then in every sixth, and on and on, until on the last trip, the assistant just had to turn the key in the hundredth cell. When the prisoners finally woke up, which ones could walk out of their cells?  Proposed solution:  Ten cells are left open after this process. Every cell that is a perfect square will remain open (1, 4, 9, 16, 25, 36, 49, 64, 81, and 100). If a number is not a perfect square, then it has an even number of divisors, therefore it will be "toggled" an even number of times and end up where it started (closed). Perfect squares have an odd number of divisors, so they will end up the opposite of where they started (open). How to make overlay still work inside lstlisting environment?
