If I understand you correctly, you have a structure containing several members of different types and you are looking for a way how you could compare instances of this struct. It could look the following way: struct X { std::string s; char c; int i; bool operator==(const X& ref) { return s == ref.s && … Read more
Use an iframe <iframe id=”iframe1″ ></iframe> Use Js to change the src i.e document.getElementById(‘iframe1’).src = yourpagepath; Thanks 7 solved Load page in div when i click button [closed]
use “objdump -D lib_file” the left column will be the ‘binary object code’ and right column – disassembled one. solved How to find object code of c++ file
In bool StatsList::NewGrade(ListType grade) there are a couple problems. i needs to persist from call to call otherwise it will always be set to 0 at the beginning of the function. I recommend giving it a more descriptive name like listindex and making it a member variable. There is no return true. The logical place … Read more
I wanted to use my own implementation of the Strassen optimization for matrix multiplication. It is highly optimized and hence has almost no pedagogical use but then I remembered that Wikipedia has actual C code in the Strassen-matrix-multiplication entry. The implementation there is not the best: it has no fallback to the naive algorithm if … Read more
Array is a bad choice for your problem as it will take N*M comparisons(N in stdInput,M in fileInput). Better put in unordered map, then you can do for (int i: fileInput) if i not in stdInput print i 0 solved Trouble setting up the loops. (C++)
Your resource is not a list but an object. Better implementation would be something like this. [HttpGet(“{id}”)] public IActionResult Get(string id) { using (var unitOfWork = new UnitOfWork(_db)) { var r = unitOfWork.Resources.Get(id); if (r == null) { return NotFound(); } return Ok(ConvertResourceModel(r)); } } 0 solved Can’t use Count() in C#
#include <iostream> int main() { // 3 strings of 100 char max (+1 nullchar) char key[3][101]; int i = 0; std::cout << “Enter the Keyword :\n”; while(i < 3) { std::cin.getline(key[i],100); i++; } for(i = 0; i < 3; ++i) { std::cout << key[i] << std::endl; } return 0; } Alternative anwser using C++ vector … Read more
if you want to ‘return ‘ a bool from a function there are several ways The obvious one is bool CheckQuote(string item, string line) { if (!line.Contains(item)) { return false } return true; } used like this if(!CheckQuote(“a”,”b”)) // error case if for some reason the method has to be void (why tho), you can … Read more
You are passing the wrong types to your constructor: “Jack” is of type const char[5] and the second argument 28.2 is of type double Your constructor though is expecting a std::vector<string> and a std::vector<double>. So the problem is your constructor is expecting a “list” of strings and doubles, what you are not giving him. Considering … Read more
To get absolute path of that file use Path.GetDirectoryName(filePath) and combine it with new file name. You will get new file path If I understood it correctly, then in your case: text1.Text contains full file path. i.e.E:\Files\sample.pdf text2.Text contains new file name. i.e. newfilename.pdf On button_ClickEvent() you want new file name path. i.e. E:\Files\newfilename.pdf Implement … Read more
As others mentioned, you are declaring void error(); but defining void error(const char* str);. Put const char* str parameter in the declaration too, inside the class. solved class and pass string as argument to method
All command line arguments you supply are interpreted by the compiler (or compiler driver, in the case of some compilers like gcc). They may then be passed on to other programs that the compiler (or compiler driver) executes to complete particular tasks. Incidentally, -o is not an optimisation setting with quite a few compilers. It … Read more
This can be done with Linq and the GroupBy function pretty easily: var input = new string[] { “welcome guys”, “guys and”, “and ladies”, “ladies repeat”, “repeat welcome”, “welcome guys” }; var groups = input .GroupBy(x => x); foreach (var g in groups) { Console.WriteLine(“{0}, {1}”, g.Key, g.Count().ToString()); } welcome guys, 2 guys and, 1 … Read more
There are many ways to do this, this is the one closest to your own code: #include <stdio.h> int main() { int y, m; printf(“Input number of months: “); fflush(stdout); scanf(“%d”, &y); m = y % 12; y = y / 12; printf(” %i Year(s) \n %i Month(s)” , y, m); return 0; } The … Read more
