rakhimjonova13 — Fri, 10 Feb 2023 11:42:04 +0000

Bugun biz While mavzusini o'tik bu mavzu qogan mavzularga nisbatan boshqacha va qizqro mavzu.Bu mavzuda birhil kodlarni qayta qayta yozmasdan While dan foydalansa boladi:

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

int i = 1, x;
  int sum = 0;
  cin >> x;
  while(i <= x){
    sum += i;
    i++;
  }
cout << sum << endl;


  return 0;
}
mana While ga misol

if else ohirgi darsimiz

Bugun if else da ohirgi dars misolani ishlaymiz 
#include <iostream>
using namespace std;
int main(){

int a,b,c;
  int a1,b1,c1;
  int strike = 0, ball = 0;

  cin >> a >> b >> c;
  cin >> a1 >> b1 >> c1;


  if(a == a1){
    strike++;
  }
  if(b == c1 || c == b1){
    ++ball;
  }
  if(b == b1){
    ++strike;
  }
if(a == c1 || c == a1){
  ++ball;
}
if(c == c1){
  ++strike;
}
if(a == b1 || b == a1){
  ++ball;
}
  if((b == c1 && c == b1)){
    ++ball;
    }
    if(a == c1 && c == b1){
    ++ball;
      }
       if(a == b1 && b == a1){
    ++ball;
         }
   << strike << "S" << ball << "B";
bu bizani ohirgi mavzuyimiz 
keyingi darsdan boshqa mavzu otamiz

  return 0;
}

c++ da if(){} belgisi

rakhimjonova13 — Wed, 18 Jan 2023 11:52:52 +0000

if(){} belgisi da ikta yoki ikitadan ortiq shartlar berish mumkin
yana cout lar ham 2ta yoki 2tadan ortiq yozish mumkin

@dawrou

c++ da <> belgilari

rakhimjonova13 — Wed, 18 Jan 2023 11:49:15 +0000

< bu belgi kichik belgisi > bunisi katta belgisis 
&& bu belgi yoki belgisis bolib bunda bita taraf tori bolsa bita taraf notori bolsa hato chiqadi
|| va belgisi bita taraf tori chiqsa ikinchi taraf tori chiqadi

C++da assigment operator

rakhimjonova13 — Fri, 23 Dec 2022 13:38:18 +0000

= bu assigment operator buni vazifasi qiymatni chiqaradi






int a = 10;
  string ism = "Davron";

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

  a = 20;
  ism = "kimsan";
  cout << a << endl;
  cout << ism << endl;




  return 0;

C++da sonlarni bolish

rakhimjonova13 — Wed, 21 Dec 2022 11:29:22 +0000

sonlarni bolganda iki hil javob chiqadi foizi yoki butun   butunini olish uchun mana shu kodlardan foydalaniladi

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

  int son;
  cin >> son;

 cout << son /100 ;





  return 0;
}

foizini olish uchun esa



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

  int son;
  cin >> son;

 cout << son /100 % 10 ;





  return 0;
}

c++ da A=> a ga ozgartish

rakhimjonova13 — Fri, 16 Dec 2022 14:19:49 +0000

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

bu kata Adan kichkina aga ozgartiradigan kod



using namespace std;
int main (){
 char a;
  cin >> a;
cout << char(a-32);


  return 0;
}

Bu esa adan Aga ozgartiradi
