I am wondering if anyone has any insights on the performance benefit (or
detriment) of declaring local variables instead of referencing members.
Is allocating memory for a new variable more efficient than repeatedly
referencing the member in a loop?
Maybe using a string isn't the best example, but hopefully you get the
idea!
* example (referencing member):

As everybody knows, C uses a zero delimited unbounded
pointer for its representation of strings.
This is extremely inefficient because at each query of the
length of the string, the computer starts an unbounded
memory scan searching for a zero that ends the string.
A more efficient representation is:
struct string {

Dear all,
i need to parse billions of numbers from a file into float numbers for
further calculation.
i'm not satisfied with the speed of atof() function on my machine(i'm
using visual c++ 6).
so i wonder is there any faster way to parse string(char array) into
float number.

Hi all,
This is a question about the efficiency of the code.
a :-
int i;
for( i = 0; i < 20; i++ )
printf("%d",i);

Efficiency
I've never stumbled on any discussion of efficiency of various methods of coding, although I have found posts on various forums where individuals were concerned with efficiency. I'm not concerned when dealing with user typing, but I am if a procedure is called by a query.
Does the VBA compiler generate "in-line" code for some apparent function calls? For example, y = Abs(x) might be compiled as y = x & mask. The string...

I have a comma delimited file to parse up. So I figured I will go line by line and parse them up. Now efficiency is the top priority here. So I figure I can use the old-school C approach or use std::string. The way I see it I could (assuming infile is a valid std::ifstream)
char buffer ;
while (!infile.eof () && !infile.bad ())
{
// Get the next line in the file
infile.getline (buffer, 4095);
// If fail bit is set it means we...

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,...
