Relation Operator
Relation Operator- bu 2 yoki undan ko'p bo'lgan o'zgaruvchilarni qaysi biri katta,kichik,yoki tengligini bildirib beradi.

Relation Operator - Aloqa Operator. chap va o'ng tomonlardagi munosabat.

Natija har doim True yoki False.
True 1,False 0 qaytardi.
c,cpp tilida 0 dan boshqa har qanday qiymat True yani Rost deb hisoblanaldi.

Relation Opertor katta kichik va tenglik belgilari shu ko'rinishda keladi;

<,<=,==,>,>=,!=;

cpp
  int a = 14;
  int b = 78;
  int c = a < b ;

< (Operator) - chap tomondagi o'ng tomondagidan kichik,ya'ni chap tomondagi o'zgaruvchi o'ng tomondagi o'zgaruvchidan kichik
Masalan;



#include <iostream>
using namespace std;
int main (){

<=(Operator) - chap tomondagi o'ng tomondagidan kichik yoki teng ya'ni chap tomondagi o'zgaruvchi o'ng tomondagi o'zgaruvchidan kichik yoki teng
Masalan;

cpp
#include <iostream>
using namespace std;
int main (){
  int a = 6;
  int b = 5 + b++;
  int c = a >= b ;
 cout << c;
return 0;
}

==(Operator) - chap tomon o'ng tomong teng ya'ni chap tomondegi o'zgaruvchi o'ng tomndegi o'zgaruvchiga teng;

cpp

include

using namespace std;
int main (){
int a = 4;
int b = 9 - 5;
int c = a == b ;
cout << c;
return 0;
}

(Operator) - o'ng tomon chap tomondan katta ya'ni o'ng tomondagi o'zgaruvchi chap tomondagi o'zgaruvchidan katta;
Masalan;

cpp

include

using namespace std;
int main (){
int a = 6;
int b = 9 - 7;
int c = a > b ;
cout << c;
return 0;
}

=(Operator) - o'ng tomon chap tomondan katta yoki teng ya'ni o'ng tomondagi o'zgaruvchi chap tomondagi o'zgaruvchidan katta yoki teng;
Masalan;

cpp

include

using namespace std;
int main (){
int a = 174;
int b = a - 87;
int c = a >= b ;
cout << c;
return 0;
}

!=(Operator) - chap va o'ng tomonlar bir xil emas ya'ni chap tomondagi o'zgaruvchi o'ng tomondagi o'zgaruvchi bilan bir xil emas ;
Masalan;

cpp

include

using namespace std;
int main (){
int a = 66;
int b = 47 + 19;
int c = a != b ;
cout << c;
return 0;
}

LOGICAL OPERATOR

Charos1mm — Wed, 11 Jan 2023 14:28:14 +0000

Bir yoki bir necha shartlarni solishtirish va ularni to'g'ri yoki noto'ri ekanligini aniqlash.

! - YO'Q.
&& - VA.
- YOKI.
Natija har doim True yoki False.
True 1,False 0 qaytardi.
0 dan boshqa har qanday qiymat True yani Rost deb hisoblanaldi.

#include <iostream>
using namespace std;
int main() {
  int  a = 7;
  int  b = 3 + a;
  int  c = a && b ;

  cout << c;
return 0;
  }

#include <iostream>
using namespace std;
int main() {
  int  a =27;
  int  b = 67 + a;
  int  c = ++a < 5  --b < 3 ;

  cout << c;
return 0;
  }

Dasrligimiz kundan kunga qiyin va qiziqarli bolib bormoqda .

ASSIGMENT

Charos1mm — Fri, 23 Dec 2022 13:47:43 +0000

Biz bugun assigmentni organdik .


int main1() {

int a= 10;
string ism = "davron";
cout << a << endl;
cout << ism << endl;
a =20;
ism ="kimsan";
cout << a << endl;
cout << ism;
 return 0;

}

Hatoki masalalar yechishni ham organdik.

#include <iostream>
#include <cmath>
using namespace std;
int main () {
double L;
cin >> L;
  float PI = 3.14;
  float r = L/ (2*PI);
  float S =PI * (r * r);
  cout << round (S);
return 0;
}

KUNDAN KUNGA DARSIMIZA QIZIQARLI BOLIB BORMOQDA.BIZLAR JUDA KOP NARSALARNI ORGANDIK .
MASALAN BULARGA MISOL: # include <iostream > bu digani kutbxona chaqirish digani, /degani bu butun son chiqarish degani,%esa qoldig'ini chiqarib beradi,assignment ham organdik.

Assignmentbiz yozgan ko'dlarni qisqartirib yozib beradi.

b = b + a; // b += a
b = b - a; // b -= a
b = b / a; // b /= a
b = b * a; // b *= a

* / % + -bugungi darsimiza

Charos1mm — Tue, 20 Dec 2022 12:15:31 +0000

Biz bugun / ni organdik.

int A= 7;
int B= 3;

cout << 3 / 10 << endl;  
cout << 3 % 10 << endl;  

return 0;

}

Bizlar bo'lishdan foiz chiqarishni organdik.

int son;
cin>> son; 
cout << son /10000 << '!'; 
cout << son / 1000 % 10 << '!';
cout << son /100 % 10 << '!';
cout << son / 10% 10 << '!';
cout <<son % 10 ;
return 0;
}

Kunlarni chiqarishni ham organdik.

int main4(){
int N;
cin >> N ;
cout << "Sun Mon Tue Wed Thu Fri Sat" << endl;
cout << setw(3) << N;
N = N % 31 + 1;
cout << setw(4) << N;
N = N % 31 + 1;
cout << setw(4) << N;
N = N % 31 + 1;
cout << setw(4) << N;
N = N % 31 + 1;
cout << setw(4) << N;
N = N % 31 + 1;
cout << setw(4) << N;
N = N % 31 + 1;
cout << setw(4) << N;
return 0;

CHAR HAQIDA MA'LUMOT

Charos1mm — Fri, 16 Dec 2022 14:34:42 +0000

Char bugungi mavzuyimiza, oz ichiga faqatgina 1ta belgini oladi.

Misol uchun:

`cpp
int main1() {
int a = 10;
float b = 10.5;
double c = 10.232153515136;
string d ="ikkichilar";

// char => character(belgi);

char belgi = 65;
int son = 'A';
// int son = 3;

cout << belgi << " " <<son;
return 0;
}
`

_Charda faqatgina 1ta dona belgini saqlashimiza mumkun.Undan kopni saqlay olmaymiz.Charni intga ,intni esa charga ozgartiramiza.
_

Misol uchun:

`cpp

include

using namespace std;
int main3(){
int a =65;
char b ='z';
cout << char (a);
cout << endl << int (b);
return 0;
}
`
Chardan A va a belgilarni qanday qilib chiqarishni organib oldik.

Misol uchun:

`cpp

include

using namespace std;

int main (){
char a;
cin >> a;
cout << char (a+32);

return 0;
}
`
BUGUNGI DARSIMIZA CHAR HAQIDA BOLDI.

C ++dan kop narsalarni orgabndik

Charos1mm — Wed, 14 Dec 2022 15:01:04 +0000

C++da bugun yangi kutbxonani o'gandik.# include <iomanip>bu yangi kutb xona.

Tugulgan kun va oylar chiqariwni organdik.



int kun,oy;

cin>>kun >> oy;
cout <<"Birthday is "; 
cout<<setw(2) << setfill('0')<<kun<<'-';
cout<<setw(2) <<setfill('0')<<oy <<'.';

C++dan kasr sonlarni ciqariwni organdik.




int main2 (){
int eni,boyi;
cout<<"Tortburchaknin enini kiriting:";
cin>>eni;
cout<<"Tortburchakning boyini kiriting:";
cin>>boyi;
  cout<<" Tortburchaknin yuzi:"<< eni*boyi;
}

BUGUN MANAWU DARSLARNI ORGANDIK.
C++dan

C++ga kirish

Charos1mm — Wed, 14 Dec 2022 14:49:00 +0000

Biz bugun C++ darsida ishlashni organdik.Replit.comesa qanday foydalanishni bilib oldik unda kamentlarni kodlashni organib oldik.

  /*cout << "Salom guruhdegilar\n";
 cout << "salom nima "<<end ;
  cout << "salom nima ";*/

Replit.comdan C++dan foydalanish
#include <iostream> biz foydalanmoqchi bolgan kutubxonamiza.
using namespace std;bundan esa hadib std:: cout ishlatmaslig ucun foydalandik.
RUNdan esa qanday qilib ekranga ciqarib olishnin bilib oldik.

Biz c++dan yana kop narsalarni o'rgandik.
C++dan O'zgaruvchilar turlarni organdik

adata tip nom=qiymat;

-------------Ozgaruvchilar turlari---------------
   int=>integer ya'ni faqat butun son saqlaydi;4byte  
  string=>faqat tekstlar saqlash ucun;4byte
  char=>faqat 1ta belgi saqlash ucun;1byte
 float=>faqat kasr son saqlash ucun;4byte
*/

 int yosh =17;
string ism =" Charos";

  cout<<" Salom"<<ism<<endl;
  cout<<"men"<<yosh<<" daman";
  return 0;
}

cpp
*C++ * kopaytirish,qoshishni,ayirishni organdik

int main4(){
 int son,son1,son2;
  son1=10;
  son2=son1+20;
  son=son1+son2;

  cout<< son << endl; //40

  son=son*3;
  cout<< son<<endl;
  string ism,a,b,c;
  ism=" Charos";

  b=" Nima gap";

  cout <<a<<ism<<b<<endl;

  b="Qalaysan";
  cout<<b;
return 0;

`int main6(){
