Polymorphism replaces switch statements, making the code more
compact/readable/maintainable/OO whatever, fine!
What I understand, that needs to be done at the programming level, is
this:
a switch-case has a variable (most probably an enumeration) &
associated symbols or integral value. Selection is made, base on what
symbol/value the variable holds. So

Hi,
My son is writing a program to move a character. He is
using the numbers on the keypad to indicate the direction
of movement:
7 8 9
4 5 6
1 2 3
Each number has a direction except for '5'. So in
his switch statement, he omits a case for '5':

Hi all,
I don't have a copy of C standard at hand and so anyone of you can
help me. I have always wondered how switch statements are so efficient
in jumping to the right case (if any)? Can anybody point me to the
innards of it please?
Sorry if this is OT on clc and more relevant to comp.compilers. I am
confused here too.

Is a switch more efficient than an if statement? I observe thru the debugger
that a switch statement jumps directly to its case handler where as an if
statement examines all conditions sequentially. Is that a trick of the
debugger or is a switch quicker by O(n).

I'm having problems with a switch statement that is wrapped in a
foreach statement so that each index in an array is evaluated against
the switch statement. The switch/case will then return some output for
display.
I have a long list of classes for the upcoming semester. Each one has a
checkbox to the right that has the following code. <input
type="checkbox" name="course" value="i"> where i increases linearly
with each class, i.e. first...

Hello, I have four textboxes that the user enters the price per gallon
paid at the pump, the mileage per gallon and I would like to then
calculate the cost per gallon and use a switch statement to pull a
value based on the price per gallon.
For example if the price of fuel is 2.44 per gallon and the enter that
they get 5.9 miles per gallon the cost of that mile is $.41. Then based
on the cost per gallon of 2.44 we might pay them another...

Hi Folks,
I'm experimenting a little with creating a custom CEdit control so that
I can decide on what the user is allowed to type into the control. I
started off only allowing floating point numbers then added support for
putting in lat/lon coordinates.
I tried this little piece of code inside the OnChar function but
compiler complained about missing ';' after "case _T('W'):"

Hi everyone,
This is the first time iam posting excuse me if iam making any
mistake. My question is iam using a switch case statement in which i
have around 100 case statements to compare. so just curious to find
out is it effective to use this method?? or is there is any other
alternative method present so that execution time and code size can be
reduced??
Thanks in advance.

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
