[ad_1] This is because your function has a possible code path that lets the if’s fall through without the function returning anything. Technically it shouldn’t be possible, but the compiler has noticed the possibility, and won’t let you continue. Your function should look more like this: Degree climate_control(Degree degree) { if (degree == LOW_TEMPERATURE_BOUNDARY) { … Read more
[ad_1] HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument(); doc.LoadHtml(html); var teams = doc.DocumentNode.SelectNodes(“//td[@width=”313″]”) .Select(td => new TeamClass { TeamName = td.Element(“a”).InnerText, TeamId = HttpUtility.ParseQueryString(td.Element(“a”).Attributes[“href”].Value)[“ItemTypeID”] }) .ToList(); 14 [ad_2] solved How can i parse html string [closed]
[ad_1] Are there files like DLLS formed? No. Ruby is an interpreted language much like JavaScript, Python, and PHP. If there is not a main() defined, what is the entrypoint for a program? Well, what do you define as an entry point? If you mean running a particular file, then anything not wrapped in a … Read more
[ad_1] Why use C# and not assembler? Because it’s a higher level abstraction that allows you to do the same things more quickly and with fewer errors. You would use a CEP product like Apama for the same reason. It’s designed to make even driven programming quicker and easier than using other technologies. [ad_2] solved … Read more
[ad_1] I just modified your function a little. Here is the code #include <stdio.h> #include <math.h> int prime(int a) { int b=2,n=0; for(b=2; b<a; b++) { if (a%b==0) { n++; break; } } return(n); } int main(void) { int c, answer; printf(“Please enter the number you would like to find is prime or not= “); … Read more
[ad_1] Your unroll doesn’t help with the FP latency bottleneck: sum + x + y + z without -ffast-math is the same order of operations as sum += x; sum += y; … so you haven’t done anything about the single dependency chain running through all the + operations. Loop overhead (or front-end throughput) is … Read more
[ad_1] Assuming that the .txt file contains one word per line, here is a simple solution: string[] keywords = System.IO.File.ReadAllLines(@”C:\Temp\keywords.txt”); List<string> nomatch = new List<string>(); System.Net.WebClient wc = new System.Net.WebClient(); foreach (string word in keywords) { string response = wc.DownloadString(“http://www.website.com/search.php?word=” + word); if (response != null && response.Contains(“No matches found”)) nomatch.Add(word); } if (nomatch.Count > … Read more
[ad_1] Although those examples come from a different language, I think they are the same as operator precedence in C. In general, you’d be better off using a reference for the C language, such as the C standard, or a summary such as the one in Wikipedia. However, I don’t believe that is actually what … Read more
[ad_1] In C++, you can utilize lambda functions to achieve something similar: #include <iostream> using CmpFunc = bool(float, float); CmpFunc* condition(char op) { switch (op) { case ‘>’: return [](float a, float b) { return a > b; }; case ‘<‘: return [](float a, float b) { return a < b; }; case ‘=’: return … Read more
[ad_1] I don’t see an issue, but if you’re asking if your approach is improvable, yes. I would simply use a class with these properties(inclusing gender). class Person { public bool IsFemale { get; set; } public string Name { get; set; } } Now you can create a single collection, for example a List<Person> … Read more
[ad_1] Ultimately, this is the same problem mentioned here: How can I use EF to add multiple child entities to an object when the child has an identity key? If you have a auto generated PK and attempt to do an Add after doing a previous udpate/delete on the same context, it will crash because … Read more
[ad_1] Pointers-to-members are a special gadget in C++ that tell only tell you about a which member of a class you want without pertaining to any object. You need to combine a pointer-to-member with an object instance in order to obtain an actual member, whether it be a data or a function member. Think of … Read more
[ad_1] You should try %d instead of %o. Because %o will print octal integers and your expected answer is of base 10 (decimal). [ad_2] solved Why my program is skipping the digit 8 and 9? [duplicate]
[ad_1] Do you know about integer limits? A char value takes up 1 byte. A byte is usually 8 bits. To calculate the limit through the number of bits, the calculation is 2^n-1 meaning an integer with 8 bits has a range from 0 to 255 when unsigned. Since your variable is signed, it allocates … Read more
[ad_1] If you store Ids as comma separated string – you always have TABLE/INDEX scan. If your table is small it can be enough. With SecondaryTable table which stores Ids associated with main table there a lot of other plans: You can leave as is and trust or not DB Engine optimiser query = query.Where(x … Read more
