This example just illustrates how this keyword can be used. int a = 10; // Assume that type of variable 'a' is not known here, or it may // be changed by programmer (from int to long long, for example). // Hence we declare another variable, 'b' of the same type using // decltype keyword. de...
program ForLoopWithContinueAndBreaks; {$APPTYPE CONSOLE} var var i : integer; begin for i := 1 to 10 do begin if i = 2 then continue; (* Skip this turn *) if i = 8 then break; (* Break the loop *) WriteLn( i ); end; WriteLn('Finish.'); end. Outpu...
program repeat_test; {$APPTYPE CONSOLE} var s : string; begin WriteLn( 'Type a words to echo. Enter an empty string to exit.' ); repeat ReadLn( s ); WriteLn( s ); until s = ''; end. This short example print on console Type a words to echo. Enter an empty string to exit....
To influence property lookup, the get handler must be used. In this example, we modify property lookup so that not only the value, but also the type of that value is returned. We use Reflect to ease this. let handler = { get(target, property) { if (!Reflect.has(target, property)) { ...
std::async: performs an asynchronous operation. std::future: provides access to the result of an asynchronous operation. std::promise: packages the result of an asynchronous operation. std::packaged_task: bundles a function and the associated promise for its return type.
We will look at a simple dispatch event with the example usage. (ns myapp.events (:require [re-frame.core :refer [reg-event-db]])) ...
A for loop iterate through items in an array program ArrayLoop; {$APPTYPE CONSOLE} const a : array[1..3] of real = ( 1.1, 2.2, 3.3 ); var f : real; begin for f in a do WriteLn( f ); end. Output: 1,1 2,2 3,3
One problem with the PIVOT query is that you have to specify all values inside the IN selection if you want to see them as columns. A quick way to circumvent this problem is to create a dynamic IN selection making your PIVOT dynamic. For demonstration we will use a table Books in a Bookstore’s dat...
program WhileEOF; {$APPTYPE CONSOLE} uses SysUtils; const cFileName = 'WhileEOF.dpr'; var F : TextFile; s : string; begin if FileExists( cFileName ) then begin AssignFile( F, cFileName ); Reset( F ); while not Eof(F) do begin ...
