What is the purpose of static keyword in array parameter of function like “char s[static 10]”?
...Note that the C Standard does not require the compiler to diagnose when a call to the function does not meet these requirements (i.e., it is silent undefined behaviour).

How do I get my C# program to sleep for 50 msec?

Why does this assert throw a format exception when comparing structures?
...d that's what's failing. Ouch.
Indeed, we can prove this really easily by fooling the formatting to use our parameters for the expected and actual parts:
var x = "{0}";
var y = "{1}";
Assert.AreEqual<object>(x, y, "What a surprise!", "foo", "bar");

Assert.AreEqual failed. E...

Why are const parameters not allowed in C#?
It looks strange especially for C++ developers. In C++ we used to mark a parameter as const in order to be sure that its state will not be changed in the method. There are also other C++ specific reasons, like passing const ref in order to pass by ref and be sure that state will not be changed. ...

}
return $results;
