No, it does not support regex. Read the documentation before asking. On the other hand, that’s precisely how it works so again Read the documentation, i.e. You give it all the possible delimiters. Check it here #include <stdio.h> #include <string.h> int main(void) { char example[] = “exa$mple@str#ing”; char *token; char *pointer; pointer = example; token … Read more
UPDATE: My initial thoughts as described below were found as not true: See: C++ slicing in Java / C# Original Answer: If I understood correctly this is a theoretical question. REDUCING slicing can be done by not defining new members in the derived class. slicing occurs when assigning an instance of a derived class to … Read more
A three dimensional vector follows the same format that a 2 dimension vector has. If A, B, C … are defined as std::vector<std::vector<double> > A (6,std::vector<double>(6)); Then their type is std::vector<std::vector<double> >. To create a vector that will hold 8 of those then you need to use std::vector<std::vector<std::vector<double>>> someName(8); If you want to have the … Read more
In C++20 and later auto lambda20 = []<class F, class…Ts>(F &&fn, Ts &&…args) { return std::forward<F>(fn)(std::forward<Ts>(args)…); }; In C++pre20 : C++11,14,17 auto lambda14 = [](auto &&fn, auto &&…args) { return std::forward< std::conditional_t< std::is_rvalue_reference_v<decltype(fn)>, typename std::remove_reference_t<decltype(fn)>, decltype(fn)> >(fn)( std::forward< std::conditional_t<std::is_rvalue_reference<decltype(args)>::value, typename std::remove_reference<decltype(args)>::type, decltype(args) >>(args)…); }; Example #include <iostream> using namespace std; int main() { auto lambda20 … Read more
The problem was not in the code. In my Makefile, I mistakenly put $^ instead of $< as below. %: %.c include/*.h $(CROSS_COMPILE)gcc -g -fmax-errors=5 -DQEMU -I$(AXPUDIR) -I$(INCDIR) $^ -o $@ So the make tried to compile the header file (which I put as prerequisite, to make it recompiled when I change the header file) … Read more
Removing the two dashed lines in front of delete[] * it; solved the problem. 1 solved Reuse vector in loop outputs “Killed” after few iteration [closed]
You can parse your String as DateTime like var text = “24/02/2017 13:57:53”; var dateTime = DateTime.Parse(text); And then you can access the time like var time = dateTime.TimeOfDay; 0 solved How to get time only with date and time in C# [closed]
An unhandled exception of type ‘System.ArgumentOutOfRangeException’ occurred in System.Windows.Forms.dll This is because it can not find the element in you collection of images you are looking for.

This: sum=(limit*(2*1+(limit-1)*1))/ 2; actually is the same as this formula: where Sn denotes the sum of n terms, n is the number of terms(limit) and a1 is the first term of the AP and d is the common difference. All this information is found in the Wikipedia page for arithmetic progressions. solved How the formula … Read more
Declaring the two double values (arrays) as variables in the class should allow you to make use of them everywhere in the code for that class. class X { double[] value1; double[] value2; protected void btn1_Click(object sender, EventArgs e) { double[] val1 = {…}; value1 = val1; double[] val2 = {…}; value2 = val2; } … Read more
The best thing is to leave the fan blowing, while you don’t need the temparature in the processor, but in the room. Therefore the fan needs to blow it into your room. Not to say that your processor needs cooling in order to maintain a reasonable life time. As an collatoral benèfit the fans consumes … Read more
You must declare func2 before newNode. Forward references are not possible. possibly, you DID declare func2 before but it had a compile error itself, please check further above in the log. By the way, newNode is not “the struct”. “The struct” is that variable what you have named node and is not declared, which does … Read more
Declare a class scoped variable and in the load event/constructor call you reference your main form. Not the best practice but you dont provide too much information about what you are trying to accomplish.. public static Form1 form; public class Foo { public void FooVoid() { //Form1.FormVoid(); //Then you have a reference to your Form1 … Read more
