your friends have obviously no knowledge of the real life ! getting out of school right ?
take many good application around the world:

- MS Office
- Notepad++
etc...
what language are they written in ? C/C++ *sadly*

maybe, maybe not, depends on what you do, and who you do it for. You might never use .Net in your life, depending on your employer. You might end up writing an Ada to .Net translator and crying about it here. Until you get employed you won't know, don't burn all your bridges in one direction before you find out where you will need to go.

The new framework makes your life easy, but when you need to do some thing beyond that few level deeper than fram work, you should alway do it on your own.
Belive me, If you are logically strong enough, you can RULE... (regardless of technology..)to the best of my knowledge.., framework knowledge and syntax are something always avaliable few click away,
Most of the lower level stuff needs C/C++ or some thing very close to them syntatically.
So dont worry.. thing/versions may get enhanced and renamed, unless there is something new, with which you can program with eyes and thoughs directly to a chip/memory using IR rays with 1 sec. which in turn through the error directly into your brain(tooo much scientifiction  )

hi everyone,
i have one more problem in my program.. how to define and declare the new function. because in VC++ many sourcr filesand many header file are there know so i am in confusion that in which file i have to define and declare the function. dont think that these are silly ot u guys but i am fresher 2007 passed out BE.so please help me out.please send me the fomat..
thanu in advance,

(1) You really need good C++ book.
(2) Usually function declarations go inside header files (.h), function definitions go inside source files (.cpp).
for instance (header file):
int square(int x);
(source file)
#include <iostream>
#include "myfun.h"
void main()
{
int n;
n = 5;
std::cout << "square of " << n << " is " << square(n) << std::endl;
}
int square(int x)
{
return x*x;
}
</iostream>

even a C book would do.
CPallini wrote: // file myfun.h
int square(int x);
to be exact, the header file should be:
#pragma once //or anything similar
int square(int x);
for my part, i'd even prefer to see the function delaration in its own header (like you do), but its definition in another compilation unit than main()...
but that's a matter of taste
anyway, the OP seriously need to learn C/C++ before asking such questions !

(3) if you have one header file and one source file, as in my oversimplified model, then you have to put main inside the source and don't need to protect the header against multiple inclusion .

uh... I hate to burst your bubble... but that sounds like more than "one more problem"... Get a C/C++ primer if you can afford it, or start visiting the online tutorials on the web. That is one big problem to start with.... I am well, speechless, and that is saying something!!!

u all are telling that read c++ and then do programming i agree for that but i know c++ i am learning VC++ in vc++ many source files and many header files are created when we create the project so in that no main function is there so where shall i add the defination and declaration of the function. please give some hints..
for ex:
in source files
>x.cpp
>xdlg.cpp
>
and in header files
>x.h
>xdlg.h
please help me out
thanku in advance,
savitri

I'm sorry to chatter your dreams but you don't know C++, neither C. The level of questions you are asking is from somebody who comes from VB and expect everything to be the same: you don't know how to write a switch case, you don't know how to declare a function, ...
All of these things are really the basics !
I sound maybe a little bit harsh but the best thing you can do is to buy a good book about C or C++ (depends what you want to learn) and start from the begining. It may sound like loosing your time but it's not the case. You'll be far more efficient and you won't to ask thousands of questions on the message boards each time you don't understand something.

Wow - what could be worse than someone who has no idea, and doesn't even know that ?
Nothing wrong with being a beginner, but recognise that you are one, and take the right steps to learn some basics.

My code is performing a lot of text parsing functions and I am looking at ways to optimize the code. Does any version of the microsoft run time libraries use MMX extensions if they are available? I guess the same question applies to the .NET framework as well.
|
|
|
|
|
A lot of MMX functions, 128 bit math and the like are intrinsics in the Visual Studio compilers, they are enabled by linking with the MSVCRT runtime but you don't need it to use them. They're also not especially well documented, search MSDN for intrinsics and keep digging.
Nothing is exactly what it seems but everything with seems can be unpicked.
|
|
|
|
|
I should have phrased my question better - what I meant was are functions such as strstr optimized for MMX?
Having searched a bit more Intel provide a library Intel Performance Primitives which may offer some hope.

Yes, if you want optimised standard functions that use the newer instruction, Intel libraries built with Intel's optimizing compiler backend is definitely the way to go. GNU glibc has some of the lower level i386 support functions e.g. memset written in hand optimised, GAS format, assembler but the Intel tools will optimise your whole code, post compilation.

dear all
i am doing image processing, when i would like to convert RGB to grayscale, Y = 0.3*R + 0.59*G + 0.11*B, the error occurred below:
error C2440: '=' : cannot convert from 'unsigned int' to 'unsigned int *'?
anyone help me? thanks

The message is descriptive enough: you're trying to assign an integer to a pointer. Please post Y, R, G, B declarations for further help.

You are trying to convert from a pointer to integer to an integer. And the conversion is not possible.
The error message was quite clear enough, don't you think ?

change to,
*Y = 0.3*R + 0.59*G + 0.11*B;

thanks friend
how to convert RGB image to grayscale and let RGB value become one value, for example, [(r,g,b),(r,g,b)]to [a,b], thanks a lot, however i tried, but can't, sorry in this area i am so weak.
