Here’s a version of your first example, that actually uses polymorphism: #include <iostream> #include <string> class shape { public: void setValues(int height_, int width_) { height = height_; width = width_; } virtual int area() = 0; // This is needed for polymorphism to work virtual std::string name() = 0; protected: int height; int width; … Read more
A background thread is scoped to the main thread. So it’ll run as long as the console app is alive. .Net has a rich threading library, so I leave it up to you. for ex) 1) use a delegate and call BeginInvoke 2) system.threading.Thread namespace 3) System.Threading.Tasks namespace Since threading can be daunting, here’s a … Read more

You can do the test for whether it’s home or away in the query itself. cursor.execute(“”” SELECT CASE WHEN robot_on_her_island = ? THEN ‘Last_War_on_her_island’ ELSE ‘Last_War_on_island_away’ END AS which_island, points_war_home, points_war_away FROM war WHERE ? IN (robot_on_her_island, robot_on_island_away) LIMIT 1″””, (select_robot_on_her_island, select_robot_on_her_island)) row = cursor.fetchone() if row: which_island, points_home, points_away = row if which_island == … Read more
There are a few mistakes in your logic. Let’s try this: public int move() { // make it so they can only choose 1-9 System.out.print(“Where do you want to move? “); Scanner in = new Scanner(System.in); int move = in.nextInt(); while (move < 1 || move > 9) { System.out.println(“that move is invalid must be … Read more
DrawText doesn’t work like printf or something like that. I advise you to look at the MSDN: MSDN: DrawText int DrawText( _In_ HDC hDC, _Inout_ LPCTSTR lpchText, _In_ int nCount, _Inout_ LPRECT lpRect, _In_ UINT uFormat ); You need to make a conversion to LPCTSTR, you can have a look into Google, if I find … Read more
You can follow below approach to start: Create a batch/shell file to build your project using mvn/ant/gradle command. You would need Maven/Ant/Gradle installed in your system and environment variable needs to be setup properly. Run This batch/shell file using java by taking advantage of Runtime Class. Runtime.getRuntime().exec(“cmd /c start build.bat”); To schedule your java program, … Read more

Finally I solved my problem with multidimensional arrays by using a method as below: public object[,] clear_array_nulls(object[,] input) { int m = input.GetUpperBound(0); int n = input.GetUpperBound(1) + 1; object[] temp = new object[input.GetUpperBound(0)]; for (int x = 0; x < m; x++) temp[x] = input[x, 0]; temp = temp.Where(s => !object.Equals(s, null)).ToArray(); object[,] output … Read more
You can create a Primary Key Constraint by creating a composite index with the two time values together. For example: CONSTRAINT PK_tTimeFrom_tTimeTo PRIMARY KEY NONCLUSTERED ([tTimeFrom], [tTimeTo]) This example is for MS SQL. 2 solved i want to write a SQL according to following instructions
Mathematically : As explained in wikipedia the shortest distance between a line and a dot, can be calculated as follows: If the line passes through two points P1=(x1,y1) and P2=(x2,y2) then the distance of (x0,y0) from the line is: Java implimentaion class Point { double x,y; Point(double pX, double pY){ this.x= pX; this.y= pY; } … Read more
Because in your conditions, you check if(hoursWorked[i] < 40) and if(hoursWorked[i] > 40), but there is no condition for if(hoursWorked[i] == 40). You probably wanted to use -or-equal operator on one of these conditions (>= or <=). solved Array not displaying proper output
Tested this RegEx against your test string: ([Ss]peak(.|\r|\n)*?(?=http)) The part (?=http) is the positive lookahead, which asserts that at the end of your string http follows. solved Finding a string that matches till http is found [duplicate]
