[ad_1] Use ONE of the file-handling routines in C++ or C. Mixing FILE and ifstream is certain to cause problems. ifstream input; input.open(“time.in”); input>> hrs; input.get(); … should do the trick. If you want to be picky: if (input.get() != ‘:’) … complain about bad input … 0 [ad_2] solved How can I double a … Read more
[ad_1] 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, … Read more
[ad_1] 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. [ad_2] solved C# checking a whole char for numbers [closed]
[ad_1] You could use std::string::compare() which provides the same functionality as strcmp(). std::string name1 = “John”; std::string name2 = “Micheal”; int result = name1.compare(name2); Would roughly be the same as: const char* name1 = “John”; const char* name2 = “Micheal”; int result = std::strcmp(name1, name2); [ad_2] solved Built in function to compare strings in C++?
[ad_1] You can use std::isalpha: Checks if the given character is an alphabetic character […] Example: #include <cctype> // for std::isalpha if ( std::isalpha( str[0] ) ) std::cout << “The character is an alphabetic character.” << std::endl; [ad_2] solved how to extract and check if first character in array element is a letter [closed]
[ad_1] You have got the math totally wrong. Here’s how it really is since each bit can only take on either of two states only(1 and 0) , n bits as a whole can represents 2^n different quantities not numbers. When dealing with integers a standard short integer size of 2 bytes can represent 2^n … Read more
[ad_1] Just another way using Enumerable.GroupBy and “integer division groups”: int batchSize = 120000; var fileGroups = File.ReadLines(path) .Select((line, index) => new { line, index }) .GroupBy(x => x.index / batchSize) .Select((group, index) => new { Path = Path.Combine(dir, string.Format(“FileName_{0}.txt”, index + 1)), Lines = group.Select(x => x.line) }); foreach (var file in fileGroups) File.WriteAllLines(file.Path, … Read more
[ad_1] You need to initialise your variables correctly: int firstLength = str1.length(); int secondLength = str2.length(); You’re also determining that one string is bigger than another, then proceeding to access elements in the shorter string according to the length of the longer one, which is giving you the subscript out of range error. You need … Read more
[ad_1] I don’t think your question has anything to do with printing to the console and everything to do with should you use Parse or Convert. Assuming that’s correct then you may find the following breakdown of Convert, Parse, & TryParse applicable. If it’s not correct, clarify and I’ll either edit my answer or delete … Read more
[ad_1] First you might change your if condition because you already test one time your searchArray == arr[i] if (searchArray == arr[i]) { cout << “Found value ” << searchArray << ” at index ” << i << “, taking ” << counter << ” checks !”; if (counter == 1) { cout << “We … Read more
[ad_1] https://msdn.microsoft.com/en-us/library/ms243458.aspx The third parameter in Assert.AreEqual(double, double, double) specifies the degree of accuracy you want for equality. Your code asks “is 2 within 2 of 1” which it certainly is. 5 [ad_2] solved c# Assert.AreEqual not workng
[ad_1] In C or C++, ++i means (i = i + 1) i++ means (i = i + 1, i – 1) 5 [ad_2] solved How to represent this basic expression? [closed]
[ad_1] if (validBeverage == true) were to be replced with (validBeverage) does it change the logic of the code? if yes why or whynot? [ad_2] solved if (validBeverage == true) were to be replced with (validBeverage) does it change the logic of the code? if yes why or whynot?
[ad_1] This was (apparently) changed in C11. C99§6.7/3: If an identifier has no linkage, there shall be no more than one declaration of the identifier (in a declarator or type specifier) with the same scope and in the same name space, except for tags as specified in 6.7.2.3.

[ad_1] I think to be able to call the list.Add you have to call it from a function or a void (static void main() for example) 1 [ad_2] solved List c# The name “list.add” does not exist in this context
