Here is little clearance…
Sql (4GL) what? I meant by what. In sql you just ask what you want. Not how ?(query language, but sql also provides persistent stored module “psm” or stored procedure= block of code it is stored and executed at the dbms server.)
Programming languages (what and how) int programming languages you have to wory about what you want and how you have to do it.(procedural language)
Html(presents data) you cant hide source (not code). When you do it that time your web page become invisible too and no body able to view it, that’s you want to do.
And BuRnEr says that if you don’t want to share anything (like your professional or amateur web page source) how you expect people to share something with you?
Xml (formats data ) old version is edi (it is really hot topic like ids, even lately it is big subject for cisco , also rdbs )
C++ is oop and extended version of C language
it is slower than C at run time and compile time
C is faster but how about functionality and maintainability in thousands lines of code in
this point C++ is master.And C++ has magic, smart pointers no language has that much functionality this pointers that is makes C++ master in programming life (think about all complicated software’s like os.
C++ has some major disadvantages (like Memory leaking, Buffer overflow)
Note : Now days %50 attacks about Buffer overflow. Big and big security issue, because most programs written in C++ and C. means it is big problem.
In try catch block it does not support finally block which is so important (why? Example you can feel it when you open file and during the time exception is occurred, the file remains open in this situation there are two approach first you have to close file in try and in catch block separately, this is an code duplication which is terrible think million lines of code second approach is that finally block which is not supported in C++, the finally block is executed both situation (exception occur or not) so you just close your file in finally block no code duplication.
Multiple inheritances is acceptable unlike java and C#
Functions can be used out of classes unlike java and C#
C++ is the best scientific language and it has best flexibility
C is not oop language ( please don’t say it is I saw it in forums some people believe or think it is oop language, if you believe that way just keep it for yourself )
You cant implement inheritance, polymorphism, even c does not have class concept
So it is structure language
C also has memory leakin and buffer overflow problems as C++ does
C does not have string type but it can be declared as an array
It is still good language who works low level programming
like Ethernet programming, tcp/ip , pe file format, socket programming, md5 and so on
Java oop language it is little slower than C# why?
It does not support enums and arithmetic exceptions as and C++ and C# does
It does not support operator overloading as C++ and C# do (makes big sense)
In Java all methods are virtual methods while in C#, as in C++, one must explicitly stat
which methods one wants to be virtual since by default they are not? (read about late binding)
It does not have memory leak problem
When you compare java and C# as experience, java is the expert but it does not make java to be better than C# why? Lets see it
C# is perfectly oop language
Regex is based on Perl regex which language has regex more powerfull than perl regex.
It has whatever C++ and java does that’s why C# is more complex than java.
Also in C#, being marked as volatile also prevents the Just In Time compiler from placing the variable in a register and also ensures that the variable is stored in global memory on multiprocessor systems.
It is dot net language that’s makes C# master now days as C++
.Net framework is the most powerful ide : and most C++ developers start to develop C++ applications in .net environment believe or not and they are learning C# too you can search on the web and can see statistics
http://www.serverint...tframework.aspx
1)you can almost code with any language in .Net (.net is the one now) learning .net is not easy because it is too complex believe or not it takes more than more
2)it has most powerful ADO.Net architecture
http://msdn.microsof...iewofadonet.asp
3)For creating GUI it has most rich class library and it is killing mfc
http://msdn.microsof...ms/default.aspx
4)it has CLR
http://www.clipcode....rchitecture.pdf
5)it has ASP.net
http://authors.aspal...chitecture.aspx
6)About security (Role-based security, web application security, Evidence-based security, Cryptography)
about .Net security: http://www.microsoft...al/security.asp
more and more have you read .Net architecture.????
http://www.artima.com/intv/dotnet.html
C# is born in this environment and it takes all .net poverty
It is “portable” language ….
And It is attractive language. I did not use it at the first because it was not portable…
Perl is language
Language who don’t like lines of codes like Larry Wall
Perl is powerful because it takes the best parts of other languages and combines them into one. Without other languages, there would be no Perl. (I hate lines of codes it is boring )
That’s why perl is still perl. it is still one of my and others favorite language and it is still popular it is language is never going to die like C++ at least not before than me.
There is no need to discus about perl, I can say that write code same functionality with perl and other language and compare them
But unfortunately CGI is dying
Last thing Perl is an interpretive language, which makes it easy to build and test simple programs.
For Socket programming.. and 4 100
I would talk about other languages but I don’t have time and that much knowledge because there are many , (everybody creating their own compiler and language, except me) no kidding!!!!!
but I can tell yaa, they have their own power at some point, like cobol, delphy, rubi, php, pascal, lisp, ada, vb, vb.net, zzzzzzzzz!!!(this is not yet).. as above languages do…
If I were programmer I would like to know all of them.
As I said before that, language is not important than logic, if you don’t know what you want to do and how you want to do in that time programming language is garbage….
Programming language express your mind, it is the pipe (channel) that expose your mind to real world ….
And other important thing is that learn assembly language at list little bit at list learn how to read it
Learn about UML (unify modeling language),
There is a bit advise for some of you who are saying this language is good or this is bad. that time you need to think, how much you know about that language, what makes you say that, and how much you know programming. But if who say that under 18-- and you are trying to have a fun please forgive me. If you are not than please be careful when you are posting or saying something in the public forums or environments and it may lead people wrong way as you are walking on that way. And if you are saying that this language is not good that shows your programming skills level. You can talk about advantage and disadvantages but don’t say good or bad, and before you compeare one thing with other thing you have to know both of them verrry well. It is not only valid only for programming, it is valid about all subjects.
Here is an example English is better than French, when you are saying this you have to have really strong knowledge about both of them. You don’t even know English ;
Aehu C in dangerous
I#include<stdio.h>
Int main(){
scanStr(); }
int scanStr(){
char Buff[5];
scanf(“%s”,Buff);
printf(“%s”,s);
}
other danger
main(){
int a,b;
a = 2;
b = 3;
printf("Address of a=%p b=%p\n",&a,&b);
function(a,b);
printf("a=%d\n",a);
}
int function(int x, int y)
{
int *z;
printf("Adress of z=%p x=%p y=%p\n",&z,&x,&y);
z = &y;
z++;z++;
printf("z=%p\n",z);
*z = 8;
}
for Any Correction
thanks
