Computer programs problem...
-
i am just wondering the history of computer programs...
how does the first program gets program?
How would you program a program to program programs? -
-
i think he got the ID 10 T error
-
He's asking about programming -- how does the first program ever, get programmed. And how to make a program (like VB6, Dev-C++, TurboC) that allows you to program programs.
-
read properly lah.
if you need a program to program another program...... then how do you program the very first program??
It's like you need C++ to make a program, but you need to program the C++ first.
But of course C++ have predecessors
So the VERY first program with no predecessor, how did they program that? -
Read
In the past people write machine code (kinda like binary) but now people simply write source code and let the compiler do the dirty job. -
Very very chim.... although I understand what you mean.Originally posted by Ponders:read properly lah.

If I never remember wrongly, everything started from 0 and 1. From there, they improved to the programming languages we know now. -
Secondary
Programming and coding are being taught to students at an increasingly earlier stage in secondary schools. However, software engineering is not always included in the curriculum. Many have the impression that students are adequately capable of managing projects. Development techniques beyond learning a programming syntax are required.
Secondary schools = high schools.
And I don't know how to manage memory stacks...

hmm. then how do you make a computer understand or behave a certain way after entering the binaries?
Like how do you program it to say like if you enter 1010100101, it will do something you desire?
I ask alot of questions, but these i thinks i keep wondering. haha. -

You have to know how to use those 0 and 1 first. I forgotten already. Taught to me last semester, but hardly use.Originally posted by Ponders:hmm. then how do you make a computer understand or behave a certain way after entering the binaries?

Punched cards seem to be the first form of programming... read by electrical circuits in boolean format (metal contact + mercury pool = true)...
EDIT: Actually 1 and 0 is just electrical circuits. 1 mean closed circuit, 0 means open. Like the Mark and ENAIC. -
Short Code is first programming language.
easy one.
the first program to exist was a hardware, not a software. easy too. -
double
-
actually punch cards aren't quite the first form of programming ...
that distinction belonged to Charles Babbage and his "Difference Engine" ... a mechanical device ... but the idea of programming was born from that .....
anybody know the painful imperative language called Ada ? ... it was named after charles' friend lady Ada Byron, who supposedly also helped programmed Ada ... so yeah ... the very first programmer was actually a woman ... -
interesting question but I lazy to go search for the info so this is what I know of the programming process...Originally posted by Ponders:i am just wondering the history of computer programs...

source code
assembler linker application
source codes are written in programming languages which are put thru compiler to be converted to binary(0 and 1,also called machine codes)
A better way to look at it would be thru assembly language....where the programmer writes codes for use with hardware registers and etc...low-level language....C++ and etc are consideredigh-level languageswhere a lot of the intermediate processes are not shown to the programmer...it is presumed that the programmer already knows....which may not be the case sometimes
btw....hex values are more commonly used than binary in programming...because hex is easier to see than binary... -
Then how do you program the program that compliles the program that you programme it to become a program?
-
if you're talking about the chicken and egg thingy, as some chap said above, somewhere along the line, it all started with somebody flipping bits ....Originally posted by ditzy:Then how do you program the program that compliles the program that you programme it to become a program?
if you're talking about writing compilers, trust me ... you wouldn't want to know ... just figuring out the semantics and grammers can make heads explode ...
(most 4th year undergrad or masters programs in com sci offer a compiler writing course though, go squeeze a geek at your school's com sci department for info ...
) -
very good to see someone so curious about such stuff. as one of the guys has pointed out, what you may be interested is compiler writing. you would have to deal with language parsing, object linking, compiling etc.Originally posted by ditzy:Then how do you program the program that compliles the program that you programme it to become a program?
you would also like to know more about the file format for executables. e.g. PE, ELF etc. -
Binary Codes, writes all the programming languages.
-
all the way before binaries. read the posts ^Originally posted by ShutterBug:Binary Codes, writes all the programming languages. -
good question.Originally posted by ditzy:Then how do you program the program that compliles the program that you programme it to become a program?
I dunno.
I find out this week. -
according to the expert....long long time ago...computers are made to work by switches....physical switches...to program the binary into the computer...so that programs can be written and run...so technically...the human brain is the very first compiler.Originally posted by Xcert:good question.
I dunno.
I find out this week.
