This programming allows the user to input a decimal number and converts it to octal. It displays the decimal number entered by the user and its equivalent octal value. The user is also prompted if they want to do another conversion or end the program.
Не так давно Гор Нишанов представил свой доклад: C++ Coroutines a negative overhead abstraction. В этом докладе Гор упомянул, что предложенный дизайн корутин позволяет их использовать практически в любых окружениях, в том числе и с "бедным" C++ рантаймом.
Я решил попробовать запустить корутины в следующих окружениях: обычное приложение, драйвер ОС Windows, EFI приложение. Только в одном из этих окружений есть полноценный C++ рантайм и поддержка исключений, в остальных ничего этого нет. Более того, EFI приложение вообще выполняется до старта ОС.
Я хочу рассказать о том, как мне удалось запустить корутины в этих окружениях, поговорим о том, какие проблемы существуют в асинхронном системном программировании и как их можно обойти.
QA Fest 2019. Saar Rachamim. Developing Tools, While TestingQAFest
Our daily work is comprised of testing a product and improve its quality. However, here and there, we can come to a state where we find a need to build a tool, that can make our work easierbetter.
I will share from my experience when I found myself in a situation where building a tool was needed.
We will start with a web application that allows you to know when a food delivery you ordered arrives to the office, and then we will focus on a tool that test the performance of an app from the UI side. We will do a live demo for both of them.

Rust
Why do you care about Rust? Who has the time to learn all these new languages? It seems like a new one is popping up every other week and this trend is growing at an exponential rate. Good news, a fair number of them are crafted really well and efficiently solve specific problems. Bad news, how do you keep up with all of this, let alone decide which languages to include in your companies technology portfolio.
Despite the challenges of all these new languages, a majority of developers are intrigued about the idea of becoming a polyglot, but don't know where to begin or don't have the time. In my polyglot travels, there is one language of late that is the sure-fire answer to the above questions, Rust.
In this talk I’ll explore the value behind becoming more polyglotic as a developer, how to pick languages to learn, and then dive deep in the the language of Rust. Which in my opinion, is hands down the best up and coming languages to learn.

What is risk? Many people aren't sure, but it's not just uncertainty: risk is exposure to uncertainty.
Instead of just plastering over the cracks, security should also involve reducing the size and number of cracks, reducing the opportunities for cracks to appear, reducing the class of errors and oversights that can open a system to failure instigated from the outside. We can learn a lot from other kinds of software failure, because every failure unrelated to security can be easily reframed as a security-failure opportunity.
This is not a talk about access control models, authentication, encryption standards, firewalls, etc. This is a talk about reducing risk that lives in the code and the assumptions of architecture, reducing the risk in development practices and in the blind spot of development practices.
Build a full-functioned virtual machine from scratch, when Brainfuck is used. Basic concepts about interpreter, optimizations techniques, language specialization, and platform specific tweaks.
The case for building software with privacy as a primary concern with a discussion of how privacy and secrecy differ.
This is followed by an introduction to practical cryptographic techniques with code in Go which can be used to secure both communications channels and data stores.

4. This programming accepts a number between 1
and 5 . If the user enters a right number the
programming will show an output according
to its number.

5. #include <iostream> cout<< " Enter the width : ";
#include <cstdio> cin>>wid;
using namespace std; area=len*wid;
int main() per=(2*len)+(2*wid);
{ switch (ch)
intch, len , wid , area , per ; {
balik: case 1 : cout<< " The Area is : " <<
system ("cls"); area <<endl;break;
cout<< " ***** Area - Perimeter case 2 : cout<< " The perimeter is : "

cout<< "Enter your choice here : " ; return 0;
cin>>ch; }
cout<< " Enter the length : ";
cin>>len;
http://eglobiotraining.com/
7. This programming computes for the area or
perimeter of a given rectangle given that the
user will input its length and width. After the
programming accepts the values for
dimensions of the rectangle, the programming
lets the user choose if the programming will
compute for its perimeter or area. Then the
programming will compute for whatever the
user chose and then prints the computed value.
Lastly the programming will ask the user to
press any key to end the programming.

using namespace std; cin >> x;
int main ()

}
system ("pause");
return 0;
}
http://eglobiotraining.com/
11. This programming will
display the equivalent
birthstone of each month
using switch statement.

12. #include "iostream.h"
using namespace std;
int main ()
{
system ("cls");
for (int x = 1 ; x <= 10 ; x++ )
{
switch ( x )

case 9: cout<< " nine "<<endl;break;
default: cout<< " ten "<<endl;break;
}
system ("pause");
return 0;
}
http://eglobiotraining.com/
14. This programming allows the user to input a
number from 1 to 10. If the user input a right
number,the programming will run correctly
and it will display the equivalent of the
number in words.
http://eglobiotraining.com/
15. #include "iostream.h"
using namespace std;
int main ()
{ int rem , x;
system ("cls")
cout << "Enter an integer : ";
cin >> x;
rem=x%2;
switch (rem)
{
case 1: cout<< " Odd "<<endl;break;
default: cout<< " even "<<endl;break;
}
system ("pause");
return 0;
}
http://eglobiotraining.com/
17. This programming allows the user to enter a
integer number in which it will also display if it
is even or odd after executing the indicated
operation in the programming. We all know
that the number is even if it’s remainder is 0
and odd if it’s remainder is 1.
http://eglobiotraining.com/
18. #include <iostream> fact+=1;
#include <conio.h> }
using namespace std; }
int main() if(fact>0)
{ cout<<"COMPOSITE!";
intnum, ctr=2, fact=0; else
system ("cls"); cout<<"PRIME!";
cout<<"Enter a number: "; }
cin>>num; cout<< "n";
{ system ("pause");
for (;ctr<num;ctr++) return 0;
{ }
if(num%ctr==0) http://eglobiotraining.com/
20. This programming allows the user to input a
number. This number will be test if it’s a
PRIME or COMPOSITE.
http://eglobiotraining.com/
21. #include "iostream.h"
using namespace std;
int main ()
{
system ("cls");
for (int x = 1 ; x <= 10 ; x++ )
cout << x << "t" << x*x<< endl;
system ("pause");
return 0;
}
http://eglobiotraining.com/
23. In this programming,the user is allowed to
enter a number from 1 to 10 and once he/she
enters the number the programming will
execute the operation in which it will displays
the square of the number inputted by the user.
http://eglobiotraining.com/
24. #include "iostream.h"
using namespace std;
int main ()
{
system ("cls");
for (int x = 1 ; x <= 10 ; x++ )
{for( y=1 ; <=10 ; y++)
{cout <<"#"<< endl;
}
cout << "t";
}
system ("pause");
return 0;
}
http://eglobiotraining.com/
26. This programming draw a ten by ten sharp
symbol box using the for loop.
http://eglobiotraining.com/
27. Octal is : "
#include <iostream> <<oct<<dec<<endl<<end
using namespace std; l;
int main() cout<< "Do you wish to try
again [Y/N]? : ";
{ intdec;charch;
cin>>ch;
do
}while (toupper(ch)== 'Y');
{
system ("pause");
system ("cls");
return 0;
cout<< "Enter a decimal: ";
}
cin>>dec;
cout<< " THe number in
http://eglobiotraining.com/
29. This programming converts the user’s input of decimal
number system into octal number system. The first step
in this programming is to ask the user to input an
integer of base 10(decimal). Next, the programming
will compute the value of the base 10 into base 8 or
octal number system. After the programming has
computed the value of base 10 integer to octal, now it
will output or print the answer of conversion of
decimal to octal. Then the programming will ask the
user if he/she wants to try again. The programming
accepts only Y for yes and N for a no. Lastly the
programming asks the user to press any key to end the
programming.
http://eglobiotraining.com/
30. #include "iostream" }
#include "conio.h" cout<< "Trip Executed !!!
using namespace std; "<<endl<<endl;
int main () system ("pause");
{ return 0;
charch = 'a'; }
system ("cls");
while (ch !='q')
{
cin>>ch;
http://eglobiotraining.com/
32. This programming accepts any character
such as alphanumeric and special
characters(symbols and the like). After
the input of the user, the programming
will now test the entered character. If the
programming reads the letter q or Q the
programming will end and outputs
“PROGRAM EXECUTED”.
