Let's say we have vector:
std::vector<int> intVector;
And we want to declare an iterator for this vector. An obvious idea is to use auto. However, it may be needed just declare an iterator variable (and not to assign it to anything). We would do:
vector<int>::iterator iter;

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.
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...
