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

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

Because 0 is a perfectly valid expression in C.
cat f.c void f(void) {
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,

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.
