3. Introduction

4. Machine code and assembler

Example of displaying «Hello world» in Assembler:
.model tiny
.code
ORG 100h
begin:
MOV AH,
MOV DX,
INT 21h
RET
9
; Function to display a string on the screen
OFFSET Msg ; line address
; perform a function
; return to the operating system
Msg DB 'Hello, World!!!$'
END begin
;output string
«machine code is a sequence of voltage drops»

5. The first high-level programming languages

IDENTIFICATION DIVISION.
Cobol(Common Business-Oriented
Language)
PROGRAM-ID.
HELLO-WORLD.
*
ENVIRONMENT DIVISION.
*
DATA DIVISION.
*
PROCEDURE DIVISION.
PARA-1.
DISPLAY "Hello, world.".
*
Fortran(FORmula
TRANslation)
EXIT PROGRAM.
END PROGRAM
HELLO-WORLD.
PROGRAM
HELLO
The first
high-level
programming
languages
«The entire global
financial system is
programmed on
Cobol.It is used in
banks, insurance
companies and other
PRINT*,
'Hello^World!'
END
Lisp (LISt Processing)
(format t "Hello, World!")

6. Programming languages of the 1970s and 1980s

program
hello;
Pascal
begin
Programming
languages
of the
1970s and
1980s
«Smalltalk introduced the first
integrated development
environment (IDE), which
included a text editor, a system
and class browser, an object and
property inspector, and a
debugger. This gave rise to many
of the IDEs that developers use
today, such as Visual Studio,
Xcode, and IntelliJ IDEA.»
writeln(‘Hello,
World!');
end. Smalltalk
Module name: HelloWorld.
Function [<$entrypoint>
Main
stdout cr << 'Hello World!'
]
C
#include <stdio.h>
int main (void)
{
puts ("Hello, World!");
return 0;
}

7. Modern programming languages

#include <iostream>
C++
using namespace
std;
Modern
programming
languages
«complete independence of
the bytecode from the
operating system and
hardware. “Write once, run
anywhere” - is the Java
philosophy»
int main()
{
cout << "Hello,
world!" << endl;
return 0;
}
Java
class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
Python
print('Hello, World!')

8. Conclusion

Thank you for
your
attention!

but when nothing can be taken away.»
