script papka yaratamiz

 mkdir ~/scripts

run.sh bash file yaratamiz

touch ~/scripts/run.sh

run.sh fayl ichiga quyidagi _script_ni yozamiz

#!/bin /bash
clear && gcc $1 -0 main && ./main

run.sh faylga execution ruxsatini beramiz

chmod +x~/scripts/run.sh

scripts papkasini global $PATHga doimiy qo'shamiz.

echo "export PATH=$PATH:`/scripts" >>~.bash_profile.

TERMINAL KOMANDALAR / PART 3

## alias nickname= ''

bu komandalar takroriy ishlatiladigan komandalar uchun yangi nickname ( taxallus) beradi.

## g ++ main.cpp - o dastur && ./ dastur.

main.cpp nomli faylni compilatsiya qiladi va birdaniga ishga tushiradi.

## nano

faylni terminalda ochadi.

## ./..a.out

birdaniga bitta oldingi papkaga kirib, uning ichidagi ma'lumotlarni chiqaradi.

## include

kerakli kutubxonani chaqiradi.
Masalan " iostream " (input / output)

## terminal = council std

standart namespace

## cout

std: cout, std namecpace.ni boshqalaridan ajratib turish uchun.

## int main

dasturga kirish uchun funksiya (usiz dastur ishlamaydi).

## return 0

dastur muvaffaqqiyatli bajarilganligini aniqlash maqsadida ishlatiladi.

## &&

kolandalarni bir vaqtda birin-ketin bajarilishinni ta'minlaydi.

## // (ctrl+ /)

// c++ dasturida izoh qoldirishda foydalaniladi.

## \n

new line = endl. Sonlar bilan ishlamaydi.

\ backslash -- escape characters.

OPERATORS #C++

Nilufar Isomiddinova — Thu, 12 May 2022 08:13:39 +0000

Binary

-operator deb 2 ta obyektni qabul qiluvchi operatorga aytiladi?

-Masalan :

operatory 2 ta obyekt ustida ishlatiladi.

Unary

operator deb 1 ta obyekt qabul qiluvchi operatorga aytiladi.

-Masalan :

!
operatori 1 ta obyekt ustida ishlatiladi ! true.

Moduls

-A % B is calculate the remainder of _A/B.
_
Arifmetik operatorlar
-/ amalini bajarayotganda, ma'lumotni turi muhim bo'lib ,kasr son kasr songa, butun son butun songa bo'linayotganini bilish kerak, yo'qsa misolni javobida o'zgarish bo'ladi.

_moduls faqat butun sonlar ustida amallarni bajaradi.
amallar matematika bilan bir xil ketma-ketlikda bajariladi _

SELECTION STATEMENTS

Nilufar Isomiddinova — Tue, 10 May 2022 09:28:22 +0000

C++ supports the usual logical conditions from mathematics:

Less than:

a < b

Less than or equal to :

a <= b

Greater than :

a > b

Greater than or equal to :

a == b

C++ has the following conditional statements:

-Use if to specify a block of code to be executed , if a specified condition is true
-Use else to specify a block of code to be executed , if the same condition is false
-Use if else to specify a new condition to test , if the first condition is false.

NOTE THAT' "if" is in lowercase letters . Uppercase letters (If or  IF) will generate an error'

NOTE : 'The code inside { } is the body of the /if/ statement



NOTE : `There can be more than one - else if statement but only one *if* and *else* statements.

Terminal kommandalar

Nilufar Isomiddinova — Thu, 05 May 2022 05:14:34 +0000

`pwd`

joriy papka manzilini chop etadi

`clear`

-terminaldagi hamma tekstni tozalab yuboradi

`ls`

-joriy papka ichidagi hamma narsani chop etadi
-ls-a yashirin fayllarni ham chop etadi

`mkdir`

-biror nom ostida papka yaratish

`cd`

-joriy papkadan boshqasiga o'tkazadi

`cd..`

ortga qaytish vazifasini bajaradi
