Function for Factorial in Python
... use an iterative approach:
def factorial(n):
fact = 1
for num in range(2, n + 1):
fact *= num
return fact
or a recursive approach:
def factorial(n):
if n < 2:
return 1
else:
return n * factorial(n-1)
Note that the factorial function is only defin...

Proper stack and heap usage in C++?
...elf with deleting a heap based object in an exception handler. This is why raw pointers are not normally used in modern C++, you would use a smart pointer which can be a stack based wrapper for a raw pointer to a heap based object.

Generate a random letter in Python

Why in C++ do we use DWORD rather than unsigned int? [duplicate]
...t's defined in <windows.h>.
The reason is that DWORD has a specific range and format Windows functions rely on, so if you require that specific range use that type. (Or as they say "When in Rome, do as the Romans do.") For you, that happens to correspond to unsigned int, but that might not al...

How to update a plot in matplotlib?
...wever, the shape of the data that you're plotting can't change, and if the range of your data is changing, you'll need to manually reset the x and y axis limits.

What is a “surrogate pair” in Java?
... 16-bit (two-byte) code units are used. Since 16 bits can only contain the range of characters from 0x0 to 0xFFFF, some additional complexity is used to store values above this range (0x10000 to 0x10FFFF). This is done using pairs of code units known as surrogates.
The surrogate code units are in t...
