Here is one simple way to do it. It presumes that a space separates words. It works as follows: find the index of the first space starting at the desired length of the string. if the return value is -1 (no space found), use the string length. get the substring from 0 to that index. … Read more
This can be solved much easier without requiring a regular expression: You just want to “invert” the area of the string delimited by the first and last occurrence of a “1”. Here’s an example solution: string input = “……….1…………1…”; int start = input.IndexOf(‘1’); int end = input.LastIndexOf(‘1’); char[] content = input.ToCharArray(); for (int i = … Read more
Your string looks like it’s being broken down by sections that are separated by a ,, so the first thing I’d do is break it down into those sections string[] sections = str.Split(‘,’); IT looks like those sections are broken down into a parameter name, and a parameter value, which are seperated by :. so … Read more

Issue with: template <typename T> bool operator== (const String<T>& a, const String<T>& b ) is the deduction of T, and for “hello” == String<char>(“hello”), “hello” doesn’t match const String<T>&, so that overload is discarded. What you can do is to make it non template: template <typename T> class String { // non template function. friend … Read more
why is dp initialized to 0? for using for example addition operation dp[i]+=dp[i-2<0?0:i-2]; you should use a valid value not a random value why do we subtract ‘0’*10? for conversion of char to int you substarct the ascii of ‘0’ (0x30) for example ‘1’ /* 0x31 */ – ‘0’ /* 0x30 */ = 1 and … Read more
If you want to control the precision then include #include <iomanip> and use std::cout << std::setprecision(17); to set the number of digits you want. Also float has 6 significant bits precision whereas double has 12. So whenever your string has more than 6 digits in decimal there is a possibility of loosing the precision. 7 … Read more
The data is fixed width columns so use following : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Data; namespace ConsoleApplication1 { class Program { const string FILENAME = @”c:\temp\test.txt”; static void Main(string[] args) { FIX_WIDTH fixWidth = new FIX_WIDTH(FILENAME); } } public class FIX_WIDTH { int[] Start_Position = { 0, 55, … Read more
I feel like taking risk to answer that but you can use Enumerable.All with char.IsDigit method and parse it to int like; if(myString.All(char.IsDigit)) { return int.Parse(myString); } Or better, use int.TryParse to check your string is valid integer or not. solved C# checking a whole char for numbers [closed]
Assuming words would be separated by spaces. $words40=explode(” “, $string,41); unset($words40[40]); // Discard the last element containing the remaining string Of course this will fail on punctuation marks, but since you did not mention whether your string contains something to do with human readable languages or any other value, there is no reason to assume … Read more

So it turns out I just misunderstood what was being asked. I’ve had it clarified by the course leader now. As I am now fully aware, a function definition needs to be told when a string is being entered, hence the quote marks being required.
