What's the meaning of this sentence, "0;"?

0;
The above sentence can be compiled. What does it mean? Why C++ can compile
such sentence?

Nothing.

Because 0 is a perfectly valid expression in C.
cat f.c void f(void) {
0;
}
gcc -Wall -std=c99 -pedantic -c f.c

f.c: In function `f':
f.c:2: warning: statement with no effect

Hello, Please help a VB newbie :) I'm a bit confused, reading all the MyClass, Me, My keywords of VB. I think I get MyClass and My, but Me... Can you just tell me if I get this correctly? "Me" in VB (6, 7, 2005) is exactly like "this" in C# or C++. Its meaning hasn't changed since VB 6. True or False? Many thanks,

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
