[ad_1] It looks like I was using too much memory, way too much. I only needed [257][257] in the end, not [257*257][257*257], so it was my bad. [ad_2] solved C++ Large 2D array (on the heap) crashes the application
[ad_1] I want to skip index 0. How do I do that? Further I want to replace index 0 with something else. Just start the loop from 1 instead of 0 sportsArr[0] = “Something else”; // set the first element to something else for(var i = 1; i < sportsArr.length; i++){ // do something } … Read more
[ad_1] Jeeped’s comment is a very probable reason of your code malfunctioning, unless you have Option Base 1 at the top of your code pane. so either you have/place that statement or you change the ReDim statements to ReDim B(1 To nrows, 1 To ncols) As Double moreover you must invert Next I and Next … Read more
[ad_1] int Frows = FM.length; int Fcolumns = FM[0].length; int Srows = FM[0].length; int Scolumns = FM.length; should be int Frows = FM.length; int Fcolumns = FM[0].length; int Srows = FM.length; int Scolumns = FM[0].length; and … float finAns[][] = new float[Fcolumns][Scolumns]; should be float finAns[][] = new float[Frows][Scolumns]; Start with that [ad_2] solved I … Read more
[ad_1] Actually you need to use for loop if it’s not working with filter and map. I would suggest you to access date according to keys from the above arrays let x = { “name”: “Ola”, “dates”: [ { “7.01.2020”: [1, 2, 3] }, { “8.01.2020”: [4, 5, 6] }, { “9.01.2020”: [7, 8, 9] … Read more
[ad_1] here the array with processsteptemplate = 10 is removed let arr = [ {id: 14, conditiontype: 1, processsteptemplate: 9, deleted: false, processTemplate_id: 0}, {id: 15, conditiontype: 1, processsteptemplate: 9, deleted: false, processTemplate_id: 0}, {id: 16, conditiontype: 1, processsteptemplate: 10, deleted: false, processTemplate_id: 0} ] let step = 9; let result = arr.filter((e) => e.processsteptemplate … Read more
[ad_1] Here are the ones I know of: Traditional a.k.a. plain a.k.a. C array vector unique_ptr with an array-type template argument array valarray dynarray static_vector (see also here) small_vector stable_vector There are also “variable-length arrays” and “arrays with runtime bounds”, which do not exist in C++; the former exists in C. See also this question … Read more
[ad_1] That’s a simple array containing another array so you can simply specify multiple indexes for included array: $mc_name = $_GET[‘identifiers’][‘mc’][‘nick’]; To better understand how it works think of it like assigning each array first to a variable like: $identifiers = $_GET[‘identifiers’]; $mc_array = $identifiers[‘mc’]; $mc_name = $mc_array[‘nick’]; which will essentially do the same thing … Read more
[ad_1] template<size_t stride, class T, size_t N, size_t count = N/stride> std::array<T*, count> make_2d( T(&raw)[N] ) { std::array<T*, count> retval; for (size_t i = 0; i < count; ++i) retval[i] = raw + i*stride; return retval; } this will return a array of pointers to the lower dimensions To call func2, simply do: func2( 10, … Read more
[ad_1] Try changing the last line to: print str(number) This will change the list into a printable string representation. If you want to learn more about strings and formatting, check out Chapter 7 of the Python Tutorial. Actually, the whole tutorial is pretty awesome. 🙂 EDIT: David is correct in his comment below…print converts lists … Read more
[ad_1] If I understand your question correctly, this is that I would do Scanner keyb = new Scanner(System.in); System.out.print(“Enter a sentence: “); String input = keyb.nextLine(); String[] stringArray = input.split(“,”); To see the results: for(int i=0; i < stringArray.length; i++){ System.out.println(i + “: ” + stringArray[i]); } This will work for any size sentence as … Read more
[ad_1] You can use array_walk() with anonymous function and array_unshift(): array_walk ( $array1, function( &$row, $key, $kind ) { array_unshift( $row, $kind[$key] ); }, $array2 ); eval.in demo array_walk() modify an array using a custom function. The callable function arguments are the array item (note that we have to set it by reference using &), … Read more
[ad_1] I want to get a return values 3374747372 as char or string. Casting doesn’t work in this case. You can use text formatting IO to get a hex string representation of the arrays content: unsigned char codeslink[5] ={ 0x33, 0x74, 0x74, 0x73, 0x72}; std::ostringstream oss; oss << std::hex << std::setfill(‘0’); for(size_t i = 0; … Read more
[ad_1] First for-loop fills an array of length x with user entered values. Second for-loop checks for array like this [1,2,3,3,2,1]. So it checks wether the array is reversev in the second half. Though because of the return the for-loop will be canceled at first run. So if the first entry of the array equals … Read more
[ad_1] So, it turns out that the problem was with declaring the array static in the class. Apparently what I actually wanted was to declare the variable but create it in the initialization function. I had tried this earlier, but the compiler choked and I thought that there was a problem with doing it this … Read more
