[ad_1] The problem, as M Oehm has pointed out in the comments, is with the data type that you are using for fact. It is too small to store the factorial of numbers like 100, which contain around 157 digits. You need to use an array to store the digits. Here is my approach to … Read more
[ad_1] From the documentation: If the input sequence runs out of characters to extract (i.e., the end-of-file is reached) before n characters have been successfully read, the array pointed to by s contains all the characters read until that point, and both the eofbit and failbit flags are set for the stream. … The number … Read more
[ad_1] There is no serialization library defined as part of the C++ standard. You will have to use a third party library (and requests for recommendations are off-topic for Stack Overflow), or you will have to write your own (and “how should I write a serialization library?” is probably “too broad”). [ad_2] solved How can … Read more
[ad_1] You might want to use User Settings. They’re different from Application Settings because they can be read and write between different sessions of the same applications. You can create a new setting at design time: Solution Explorer > Properties Double-click on the .settings file (this creates a new set in the default settings). Set … Read more
[ad_1] There is one semicolon after the if statement that is causing the problem. if (i!=0); { //this will always execute } change it to if (i!=0) { //this will execute if i != 0 } The compiler does not warn you because the first statement is syntactically valid. [ad_2] solved C: Weird conditional printf … Read more
[ad_1] Checked is an event (that’s why an exception is being thrown when your code looks for an handler subscription, MSDN reference), IsChecked is a Boolean and it’s probably the property you are looking for (MSDN reference). Your code should look like this: private void button_Click(object sender, RoutedEventArgs e) { if ((bool)checkBox1.IsChecked) Console.Write(“Checked”); } 5 … Read more
[ad_1] If your question is why you are getting 5: 1. So you start your loop with 1. 2. You check if 1 is smaller than 5. -> It is not, so the condition is false. 3. Then you print 1. 4. You repeat steps 1-3 again for x=2,3,4,5, because all are not bigger than … Read more
[ad_1] It’s a declaration of several variables in one line. Without obfuscation, it is equivalent to this: Mat gray; Mat smallImg( cvRound (img.rows/scale), cvRound(img.cols/scale), CV_8UC1 ); which shouldn’t need any further explanation. (In Ancient Times, when storage was sparse and terminals showed 24 lines of code, if you were lucky, using multiple-variable declarations made more … Read more
[ad_1] I believe you have string array like: string[] x = { “120”, “123”, “125”, “128”, “130”, “140”, “157”, “189”, “220”, “230”, “243”, “250” }; You have to parse each item to int and then sort them, later you can get the count like: int start = 123; int end = 150; var result = … Read more
[ad_1] You can use the isalpha function. EDIT: Your code seems to be in good way. Nevertheless, I will not do your work, but I can give you some clues! Check this tutorials to understand the if statement (you could also check the isalpha example). Don’t forget that argv is a 2 dimensional character array. … Read more
[ad_1] You can use cartesian product on sets in Java by the use of com.google.common.collect.Sets. FOR EXAMPLE Set<Integer> s1=new HashSet<Integer>(); s1.add(1);s1.add(4);s1.add(5); Set<Integer> s2=new HashSet<Integer>(); s2.add(2);s2.add(3);s2.add(6); Set<Integer> s3=new HashSet<Integer>(); s3.add(7);s3.add(8);s3.add(8); Set<List<Integer>> set=Sets.cartesianProduct(s1,s2,s3); //Give type safety warning for(List<Integer> l:set){ System.out.println(l); } OUTPUT [1, 2, 7] [1, 2, 8] [1, 3, 7] [1, 3, 8] …. NOTE If … Read more
[ad_1] Something like this: public static void deleteGrid(int startX, int startY, int width = 5, int height = 4) { // to avoid Errors, Check if indexes are in bound for grid. // if condition code goes here // then… for (int i = startX; i < startX + width; i++) { for (int j … Read more
[ad_1] if (moduleChoice == 1, gradeTestMain()); should be changed to if (moduleChoice == 1) gradeTestMain(); Likewise for other ifs. You need to close brackets – otherwise it means if (moduleChoice == 1, gradeTestMain()); which means if (moduleChoice == 1, gradeTestMain()) { ; } which means. evaluate moduleChoice == 1, throw away the result, then evalutate … Read more
[ad_1] Here’s a working code: #include <stdio.h> int main () { char x[100] = {0}; char m; int i, j; printf (“Type:\n”); for (i=0; i<99; i++) { m = getchar(); getchar(); if ((m != ‘ ‘) && (m != ‘\n’)) { x[i] = m; } else { printf (“Breaking.”); break; } } printf (“\n”); for … Read more
[ad_1] Depending on what you want you could add a fourth parameter to the File.Open method. To open the file with read only access and allow subsequent opening of the file for reading: private Stream GetFileStream(String path) { return !File.Exists(path) ? null : File.Open(path, FileMode.Open, FileAccess.Read, FileShare.Read); } This allows read and write: private Stream … Read more
