Accessing an array element from a function

This may be mostly a documention issue:

I have a function with two parameters that returns an array: text[].

I want to access just the first element of that array within
my SQL statement.

This doesn't work:

select myfunc(1,2)[1];

This does work:
select (myfunc(1,2)[1];

If that's how it's supposed to work, is that documented somewhere?

I suppose you meant

select (myfunc(1,2))[1];
If that's how it's supposed to work, is that documented somewhere?

Hey guys If I have a program (see codeSnippet1) that I compile to be called test.o Then run it as test.o n n 2 3 4 I want the code to be able to strip out the two characters at the start (always going to be 2) and store them as characters. But I can't seem to get it to work because it is a pointer to a vector of characters. However, if I only run with integer arguements and use codeSnippet2 it works fine and they convert nicely to...

Does anyone know why i can't access a form element value using dot notation in firefox, when i'm in a function. Works ok in the body. I'm trying to do this: var FarTemp = faren.temp.value; I can get at the value using the array method, the getelements by id method, and the bracket-with-the-element-name in it method. But the dot notation doesn't work, in firefox, in the function (which i have in the head).

Hello, I have a global static array of structs and want to access a given element using an identifier. I don't want to use the element subscript, because it will change if I insert elements before the element I want to access. In assembler I would simply add a label in front of the element, but this doesn't work in C++. The following programm snippet might explain what I want to do:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
