Generating random integer from a range
... properly uniform distributed solution is
output = min + (rand() % static_cast<int>(max - min + 1))
Except when the size of the range is a power of 2, this method produces biased non-uniform distributed numbers regardless the quality of rand(). For a comprehensive test of the quality of thi...
How do you load custom UITableViewCells from Xib files?
...l(withIdentifier: "cell", for: indexPath) as? MyCellClass
{
// Cell be casted properly
cell.myCustomProperty = true
}
else
{
// Wrong type? Wrong identifier?
}
And of course, the type of the associated class of the cell is the one you defined in the .xib file for the UITableViewCell su...

Get the IP address of the machine
...ing ioctl's! However, your handling of IP6 is still incorrect - you should cast to sockaddr_in6, i.e. something like tmpAddrPtr=&((struct sockaddr_in6 *)ifa->ifa_addr)->sin6_addr;

Why does this C++ snippet compile (non-void function does not return a value) [duplicate]
...long enough to hold any of the possible types and the caller might need to cast it or extract it from a union.
So the deepest cause is probably the C language creators' belief that procedures that do not return any value are just an unimportant special case of functions that do; this problem got ag...
Math.random() versus Random.nextInt(int)

Scaling by 6 doesn't alter the number of possible values, and casting to an int then forces these values into one of six 'buckets' (0, 1, 2, 3, 4, 5), each bucket corresponding to ranges encompassing either 1501199875790165 or 1501199875790166 of the possible values (as 6 is not a disvi...
Using a bitmask in C#

// The casts to object in the below code are an unfortunate necessity due to

Additional details on List<T>
Here is a little more detail on how List<T> works in case you're interested :)
A List<T> also uses a construct called a dynamic array which needs to...
What are the relationships between Any, AnyVal, AnyRef, Object and how do they map when used in Java
...or vice versa. This answer stackoverflow.com/questions/2334200/… and its cast to AnyRef just reminded me that this was still mysterious to me.

Why 0 is true but false is 1 in the shell?

Also it needs to be expected that some people cast errno to char or short at some point, or even to float. (int)((char)ENOLCK) is not ENOLCK when char is not at least 8-bit long (7-bit ASCII char machines are supported by UNIX), while (int)((char)0) is 0 independent of t...
