Introduction This tutorial will provide a step-by-step guide on how to combine two single dimensional arrays into a two-dimensional array in C#. We will discuss the different methods of combining the two arrays, as well as the advantages and disadvantages of each approach. We will also provide code examples to illustrate the different approaches. By … Read more
You append numpy array to a list, so you got 2D. Try this import numpy as np a, b, c, d, e = (np.random.randint(0,15,size=7) for i in range(5)) print(a,b,c,d,e) solved Printing random 1-D arrays in python
Introduction Compiler crashes can be a frustrating experience for C++ developers. When a compiler crashes, it can be difficult to determine the cause of the crash and how to fix it. In this article, we will discuss a common compiler crash related to C++ arrays. We will discuss the causes of the crash, how to … Read more
Since this is C and not C++, you’ll need to create your own sort program since I think qsort() can be O(n^2) worst case. Since you will be using your own sort program, you could just sort the array and the indices at the same time, treating them as pairs of elements. If there was … Read more
When you declare char string[]=”Hello” you declare an array of characters. string points to the first element of the array. * is known as the dereferencing operator. Suppose ptr is an integer pointer. *ptr will give you the content of the memory location pointed by the pointer ptr. At the time of declaration you have … Read more
There is only one problem in your code: Change for (int j=0; j<values[i].length; i++) to for (int j=0; j<values[i].length; j++) You put i++ instead of j++. 1 solved Trying to create a chessboard using an array and graphics
You don’t need new there, because you have an array of actorData and not actorData pointers, and the error is saying that it can’t convert actorData pointer to actorData. So replace this line: actorOrder[index] = new actorData(iNewOrder, sNewActor); with this: actorOrder[index] = actorData(iNewOrder, sNewActor); 0 solved input class object into array of objects [closed]
JavaScript (and hence TypeScript) uses lexical scope, meaning you cannot create an Array in an inner function and access it from outside. What you can do: Create the array in the outer function (getRessource) and return it from there. async getRessource(id) { var ref = … elided … const returnArray = []; // define it … Read more
I hope that you tried this on your own first. In any case, I am happy to help. Note the nuance on the array bounds for going forward and backward. The forward case indices go from 0 to 15. The reverse case goes from 15 to 0. In fillArray(), the code leverages the fact that … Read more
Yes. Any calculation that ends up in an int can be used in an array access. (It can throw if it’s outside the array range or negative, of course, but it’ll compile.) The JLS specifies this behavior. solved Is arithmetic allowed in a Java array subscript? [closed]
One advice, if you don’t learn for yourself, then nobody can teach you. So, please try researching a bit on the internet, or reading a good book before you post a question. Assuming this is your first mistake, and you wont repeat this without working a little on your own, i’ll provide the code and … Read more
You can retrieve the fields of each line using str_getcsv(). http://www.php.net/manual/en/function.str-getcsv.php Or just explode a second time: foreach( explode( “\n”, $text ) as $line ) { $fields = explode( ‘,’, $line ); var_dump( $fields ); } solved converting phone numbers to vcf format algorithm [closed]
Use mysql_fetch_assoc instead of mysql_fetch_row. GetRowFromDb(“`id`,`name`,`email`”, ” WHERE `id`=’1′”, “database1”, “table1″); function GetRowFromDb ($column, $condition, $database, $table) { $target=”`$database`.`$table`”; $query=”SELECT $column FROM $target $condition”; $indexedrow=mysql_fetch_assoc(mysql_query($query)); return $indexedrow; } solved Get PHP associative array from MySQL
$(document).ready(function(){ var arr = [“2″,”4″,”6″,”8″,”10”]; var index = [“1″,”5″,”9″]; var arrIndex = index.map(function(value){ return arr.indexOf(value); }) console.log(arrIndex); }) <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> 1 solved array value by jQuery
You could transform your list of words by a list of their length with map() and sort them from the longest to the shortest then just keep the first : var list = [“pain”, “poire”, “banane”, “kiwi”, “pomme”, “raisin”] var result = list.map(x => x.length).sort((a,b) => a < b)[0]; console.log(result); Or if you don’t want … Read more
