You are calling function expecting float* with a pointer to int. In C++ it is an error and your code does not compile. In C you will most likely get a warning and undefined behaviour anyway. solved Why does my function print ‘0’?
Have you tried actually setting the environment variables (CMAKE_MODULE_PATH and/or OpenCV_DIR) the error message tells you to set? You can do that from Control Panel > System > Advanced System Settings > Environment Variables See if they exist (and point to the correct path), otherwise just create them… 8 solved CMake still not working with … Read more
I solved: var all = JsonConvert.DeserializeObject<Dictionary<string, string>>(fullData); Give me a list with Key: my id Value: my value Thanks. solved Convert JSON object to List C# [closed]
In your code I cannot see checking of newline. See my code, it seems to work fine. Maybe it is solution which you are looking for. #include <iostream> #include <string> #include <sstream> using namespace std; int main() { int sum = 0; string line; while (getline(cin, line)) { stringstream ss(line); int tmp; if (ss >> … Read more
Simply: #include <fstream> #include <iostream> int main() { std::fstream file(“table1.txt”); std::string word; while (file >> word) { // do whatever you want, e.g. print: std::cout << word << std::endl; } file.close(); return 0; } word variable will contain every single word from a text file (words should be separated by space in your file). 1 … Read more
Try to use DateTime.Now.DayOfWeek. Definition: namespace System { using System.Runtime.InteropServices; [Serializable, ComVisible(true), __DynamicallyInvokable] public enum DayOfWeek { [__DynamicallyInvokable] Friday = 5, [__DynamicallyInvokable] Monday = 1, [__DynamicallyInvokable] Saturday = 6, [__DynamicallyInvokable] Sunday = 0, [__DynamicallyInvokable] Thursday = 4, [__DynamicallyInvokable] Tuesday = 2, [__DynamicallyInvokable] Wednesday = 3 } } Example: // For your case Monday == 2 … Read more
The way you are doing GetComponent is wrong. FirstCamera.GetComponent.<Camera>().enabled = true; instead you should do it like this FirstCamera.GetComponent<Camera>().enabled = true; There is no dot after GetComponent instead inequality signs with the object or class you want get. “Unity GetComponent scripting” Here is the correction to the code : if(Input.GetKeyDown(“f”)) { FirstCamera.GetComponent<Camera>().enabled = false; SecondCamera.GetComponent<Camera>().enabled … Read more
You can use fgets() to read the lines, and then strtok() to parse each line, this is a sample program, i’ve used the first element of the integer array as the array count, so you don’t need to store it in a separate variable, I did that because I assume you can have different length … Read more
Besides the bad idea of randomly assigning an integer and trying use that value a LPVOID, what it is probably happening is: Either, you are not compiling to a 64-bit system (as molbdnilo mentioned it in a comment) and therefore assigning a value greater than 32-bit to a 32-bit variable triggers an undefined behavior in … Read more
Userspace programs do exist in the Linux kernel source tree in the tools/ subdirectory. There does not seem to be a clear-cut (or any) definition of what kind of program constitutes a “tool” that requires/deserves inclusion/distribution with the kernel source. The types of utilities that do (currently) exist in the kernel source tree include an … Read more
The outer loop iterates over the lines to print. The first inner loop prints the desired number of spaces in order to have the non-whitespace characters appear center aligned. The second inner loop prints the left half of the row, and finally the third inner loop prints the right half of the row. solved How … 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
You need to get the Type instance for AA, then pass it to Activator.CreateInstance. Type myType = typeof(SomeTypeInProject).Assembly.GetType(typeName); object instance = Activator.CreateInstance(myType); 3 solved How do I create an object from a string [duplicate]
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
sigh It turns out that the member vanishing from the object when it was returned to a function outside of its class but not when returned to a function inside its class was due to Visual Studio’s intellisense getting confused somehow. a colleague with Visual Studio 2013 (as opposed to 2012 Express) does not get … Read more
