switch(var)
case 1 :
print "var = 1"
case 2:
print "var = 2"

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

C++ programmers and I tried to experience by writing 65536 switch
cases. It is too large for Windows XP and other operating system to
handle. It looks like that JMP Table obtains 256K bytes for 65536
switch cases. The program would crash when it attempts to run.
C++ Compiler does not support above 64K switch cases. I tried to
set a limit to 2048 switch cases and 4096 switch cases, but the
problem exists when program crashed again.

hello. i've been beating my head against a wall over this for too
long.
setting the variables 'z' or 'y' to differing numbers, the following
'if/else' code snippet works fine; however, the 'case' code snippet
does not. (the code's function is illustrative.)

Hi,
I just wrote a function that has over 200 "cases" wrapped in a "switch"
statement. I'm wondering if there are performance issues in such
implementation. Do I need to optimize it some way?
In terms of generated machine code, how does hundreds of cases in a switch
differ from hundreds of if-elses? Do compilers or processors do any
optimization on such structured code? Do I need to worry about the
performance, usually?

I am a convert from VB to C# so bear with me on this "conversion" question
C# switch statement seems to be the closest relative to VB's Select Case. I used VB's Select Case statement liberally. Now I find myself wanting to use "Select Case" i.e., "switch" in C# regularly, but I always have to find another way b/c C#'s switch statement only allows static or integral variables. For example, I often want to use a switch statement based on the...

Hi,
I am working on a switch module which after reading voltage through a
port pin and caterogizing it into three ranges(open,low or high),
passes this range to a function switch_status() with parameters value
and signal ID. Signal Id is used to get a user configurable parameter
inside a configuration file, which depends on the type of switch.
I have implemented it as under. Please ignore those magic numbers as I
have mimized logic to...

Can switch statements be nested?
I've got a large routine that runs off of a switch statement.
If one of the switches in switch #1 is true, that enters switch statement #2.
Some of the statements in switch #2 enter a 3rd switch.
I don't receive any compile errors except whenever I attempt to add default
switches to switches 2 or 3.

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
