[ad_1] #define SQUARE(x) (x*x) may results in a negative value, e.g. cout << SQUARE(-1-2) << endl; gets resolved in -1 – 2*-1 – 2 and produces -1. It is much better to avoid macros, but if you use this one, make it #define SQUARE(x) ((x)*(x)) [ad_2] solved Why this piece is outputting NAN (Not a … Read more
[ad_1] Based on what you’ve shown: testNum is greater than scores.length. This means that when you traverse the array by comparing your iterator (i) to testNum rather than its actual length, you will hit indexes which don’t exist. For example, let’s say testNum = 8 and scores.length = 5. Then in your code, you will … Read more
[ad_1] In saveVocabSet you’re accessing array out of bound for(int i=0; i <= arrSize; i++) // ~~ should be i < arrSize or i <= arrSize-1 Array indices should go from 0 to arrSize-1 3 [ad_2] solved C++ text file editor crashes on file edit [closed]
[ad_1] First of all, remove Player & String, you are only supposed to have the event in the parameters. You already have a config file so I don’t understand why you would need a string in the event’s parameters. Remember your class has to implement Listener if we could see your main class that would … Read more
[ad_1] See this part in the error message: NumberFormatException: Invalid int: “null” you seem to try to parse the String “null” to an int. This is not possible and will therefore throw NumberFormatException. 4 [ad_2] solved FATAL EXCEPTION: main ; Error receiving broadcast Intent
[ad_1] sizeof returns the size of the given type in number of chars, not the number of elements in the array (i.e. you have the wrong units). Therefore, ints+sizeof(ints) is incorrect, it should be ints + 5. 5 [ad_2] solved c++ fill call is creating an error [closed]
[ad_1] new Element called, therefore owned by List, so only List can delete Element. List_iter doesn’t require a destructor because it only contains a pointer. [ad_2] solved Class destructor, runtime error: Unhandled exception – Stack overflow
[ad_1] assuming int on your system is 32bit long, so the max number u can store in currentPrinter is 2,147,483,647 and minimum is -2,147,483,648. the reason you are getting arithmetic error is mainly caused because of dividing by zero but the reason you end up with divide by zero is because of the integer overflow. … Read more
[ad_1] I would suggest, inside the for loop with the call to showData(), that you add the following statement: if(cust[i]!=null) This will make sure that it never tries to read data from a space in the array where there is no customer. (Null pointer exceptions are caused by the program trying to access objects that … Read more
[ad_1] The only thing that is broken is your code. Fix would be to avoid access to system services prior onCreate() is completed otherwise there’s no setup made yet to the activity object, hence the self-explaining-the-cause exception you facing. 5 [ad_2] solved Android System services not available to Activities before onCreate() [closed]
[ad_1] Exception in thread “main” java.lang.UnsupportedClassVersionError: ASILogger : U nsupported major.minor version 51.0 It seems you have compiled it against one version of java and running on another version. Read this tutorial may help. 2 [ad_2] solved Could not find main class error [duplicate]
[ad_1] The problem is here: contentPane.add(textPane, BorderLayout.CENTER); At this point, you haven’t set up textPane. You set it up 4 lines later: textPane = new JTextPane(); textPane.setBackground(Color.DARK_GRAY); textPane.setEditable(false); textPane.setMargin(null); textPane.setContentType(“text/html”); You need to add it to the pane after initializing. Simple debugging would have fixed this problem for you. SO is not an appropriate place … Read more
[ad_1] Its quite easy to implement a replacement for atoi(): int strToInt(const char *text) { int n = 0, sign = 1; switch (*text) { case ‘-‘: sign = -1; case ‘+’: ++text; } for (; isdigit(*text); ++text) n *= 10, n += *text – ‘0’; return n * sign; } (Demonstration on ideone) It … Read more
[ad_1] Looks like something is wrong in the readWeightDeatilFromBD class in the onCreate Event !! [ad_2] solved Working on emulator, not on the device or another emulator. The set target is correct [closed]
[ad_1] This code works, I just ran it with a loop of 1000000. The easiest solution is probably to just create a new project and copy the code into that. [ad_2] solved ArrayIndexOutOfBoundsException but I can’t see where it goes out of bounds
