Can anyone either reproduce or explain the following
apparently inconsistent behaviours of __add__ and
__mul__? The class Gaussian provides a sub-bare-bones
implementation of Gaussian integers (a Gaussian
integer is a complex number x+yi for which both x and
y are
integers):
class Gaussian(object):
"""class representing Gaussian integers"""

Greetings.
I'm reading "How to think like a computer scientist: Learning with
Python" and there's a question regarding string operations. The
question is, "Can you think of a property that addition and
multiplication have that string concatenation and repetition do not?"
I thought it was the commutative property but "<string>"*3 is
equivalent to 3*"<string>". Any ideas?

I have two strings that instead of adding them together to get the sum the
are concatenating together. Does anyone know how I can get these two to
add.
while not rstemp4.eof
vservdate = rstemp4("servdate")
vdesc = rstemp4("desc")
vservhours2 = rstemp4("servhours")
vtravelhours = rstemp4("travelhours")
vtech = rstemp4("tech")

i could really use help finishing this addition program. I'm stuck on
the part that allows you to add any two large integers,up to 100
digits,(pos+pos, neg+neg, and pos+neg). could use hints ideas code
anything for neg+pos addition.
CODE SO FAR:
class INT {
int digits;
char sign;

Consider the following statement:
n+i, where i = 1 or 0.
Is there more fast method for computing n+i than direct computing that sum?

Hi,
Are 1 through 4 defined behaviors in C?
unsigned short i;
unsigned long li; /* 32-bit wide */
1. i = 65535 + 3;
2. i = 1 - 3;
3. li = (unsigned long)0xFFFFFFFF + 3;
4. li = 1 - 3;

Let me first state that I'm using Borland Turbo C++, it's relatively
old so the new string methods won't work. Anyways, first I'm trying to
collect a line of a string (with numbers, letters, dashes) into each
variable. For just numbers, it's relatively easy:
ifstream fout("s1.in");
for (a=0; a<17; a++) {
fout >> data;
cout << data << endl;
}

Hello All,
Please, if anyone can point me to the problem, I'd sure appreciate it!
I am very new to VB programming and not a programmer to begin with.
This is part of a Visual Basic 2005 Express Edition program to control a remote basketball
scoreboard display unit.
All I'm trying to do is add 5 byte variables and store the result in an integer
variable. I added a Try/Catch block to take look at things.
This exception occurs only when...

Why is the addition here adding the number as a string but the subtraction
works fine?
function boxchange(box) {
iv= dbform.ut.value
if (box.checked == true) {
iv = iv - box.value
}
else {
iv = iv + box.value

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
