if you have the line already, it’s easiest to use sscanf() to do this: long a, b; if(sscanf(line, “%ld,%ld”, &a, &b) == 2) { /* Successfully parsed two long integers, now store them somewhere I guess. */ } Note that it’s a good idea to check the return value of sscanf(), this protects you from … Read more
[*] While in pre-C++11 times implicit conversion from string literal (type const char[*]) to char* was only deprecated, since C++11 that’s an error (actually modifying it was UB earlier already). Create a modifiable array and use that instead, like so: static char argv_0[] = “pingpong”; static char *argv[] = {argv_0}; Be aware that the argument … Read more
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 solved C++ text file editor crashes on file edit [closed]
There a million ways to do this, but here is just one: HTML <div class=”box”> <header> <h2>stuff</h2> </header> <div class=”body”>things</div> </div> <div class=”box”> <header> <h2>stuff</h2> </header> <div class=”body”>things</div> </div> <div class=”box”> <header> <h2>stuff</h2> </header> <div class=”body”>things</div> </div> CSS: body { /* body hack for jsfiddle, do not use */ overflow-x: scroll; width:900px; } div.box { … Read more
I need to pass the formatter to some other methods(for formatting Y axis in a bar chart) I’ll leave the implementation details as a learning exercise for you, but one straightforward way would be to create your own subclass of DecimalFormat that overrides the various format methods, does the math, and passes the resulting modified … Read more
This means you are creating a reference for the EditText so that it can be used in another View, layout file, or in your Java code. To me, it is very much like declaring a variable in your code. String ggjon = “New to android and need an explanation”; The difference between using @+id/edit_message and … Read more

Look at the index values of the list. alist=[[1],[2]] Here alist[1] is [2], so alist[1][0] is 2. 4%1 is 0. solved Why are lists giving different value?
A for loop is better than switches and ifs when there are many different cases, all being a number in order. There are many reasons why but the best is: which is easier to read and write? 100 lines of cases or a few lines if a for loop? In this scenario if you can … Read more
Simply pass the object of the created ArrayList to the function as paramter. Here’s a short example for printing the ArrayList: Assuming you put the code inside a class, leaving a snippet here. I’ll demonstrate it with Integer examples. static void printArrayList(ArrayList<Integer> a){ for(Integer i:a) System.out.print(i+” “); System.out.println(“”); } //in the main function: public static … Read more
The question betrays some misunderstandings about what is going on here. std::array is an array object. It is an object whose storage size is the storage for its array elements. std::initializer_list is a pointer to an array (one created by the compiler). You can heap-allocate std::array for example; you cannot heap-allocate std::initializer_list. Well, you can, … Read more
$y[1] isn’t set. You need to check there’s a value before running it through explode. $y = explode( $b, $a ); if ( isset( $y[1] ) ) { $x = explode( $c, $y[1] ); return ( isset( $x[0] ) ) ? $x[0] : ”; } else { return ”; } solved Notice: Undefined offset: 1 … Read more
The most basic lisp operations are list eaters: (defun some-function (list-to-consume perhaps-additional-args) (cond ((endp list-to-consume) <end-of-list-expression>) ((<predicate> list-to-consume perhaps-additional-args) <result-expression>) (t (some-function (cdr list-to-consume) perhaps-additional-args)))) Examples: ;; The predicate is the endp expression (defun mylength (list &optional (len 0)) (cond ((endp list) len) (t (mylength (cdr list) (1+ len))))) ;; A member function (defun mymember … Read more
Suppose such a data structure existed. Then here is an O(n) comparison-based sorting algorithm: Push() every item into this data structure. Pop() them all off in sorted order. No O(n) comparison-based sorting algorithm can exist, therefore no such data structure can exist. solved How to design a data structure which supports the following operations in … Read more
