Labaratoriya №3
Mavzu: Tanlash opretori (Switch)
2.K butun soni berilgaan. Baho natijalari chiqaruvchi dastur tuzing. (1-yomon, 2-
qoniqarsiz, 3-qoniqarli, 4-yaxshi, 5-a’lo). Agar k soni 1-5 oraliqqa tegishli
bo’lmasa “xato” deb chiqarilsin.
Yechish:
#include<iostream>
#include<math.h>
using namespace std;
int main ()
{ int k;
cin>>k;
switch(k)
{
case 1:cout<<"yomon";break;
case 2:cout<<"qoniqrsiz";break;
case 3:cout<<"qoniqarli";break;
case 4:cout<<"yaxshi";break;
case 5:cout<<"a'lo";break;
default:cout<<"xato";
}
return 0;
}

2. Doiraning elementlari quyidagi tartibda nomerlangan: 1-radius R, 2-diametr
D = 2*R, 3-uzunligi L =2*pi*R, 4-doiraing yuzi S=pi*R². Shu elementlardan
bittasi berilgan qolganlarnii topuvchi dastur tuzilsin. Pi=3.14.
Yechish:
#include<iostream>
#include<math.h>
using namespace std;
int main ()
{ int k, r=3;
float d,l,s,pi=3.14;
cin>>k;
d=2*r;
l=2*pi*r;
s=pi*pow(r,2);
switch(k)
{
case 1:cout<<"radius="<<r;break;
case 2:cout<<"diametr="<<d;break;
case 3:cout<<"uzunligi="<<l;break;
case 4:cout<<"yuzi="<<s;break;
default:cout<<"xato";
}
return 0;
}
Javobi:

3. O’yin kartasi turlari brilgan: 1-g’isht, 2-olma, 3-chillak, 4-qarg’a, 10 lik
kartadan katta kartalar quyidagi qiymatlarni o’zlashtirsin: 12-dama, 13-qirol,
14-tuz. Ikkita butun son berilgan N-karta qiymati (6 ≤N≤14) va M-karta turi
(1≤M≤4) kiritilganda karta nomlarini (masalan, “olti qarg’a”) chiqarib beruvchi
dastur tuzilsin.
Yechish:
#include<iostream>
#include<math.h>
using namespace std;
int main()
{int x,y;
cin>>x>>y;
switch(x)
{
case 6: cout<<"olti ";break;
case 7: cout<<"yeti ";break;
case 8: cout<<"sakkiz ";break;
case 9: cout<<"to'qqiz ";break;
case 10: cout<<"o'n ";break;
case 11: cout<<"valet ";break;
case 12: cout<<"dama ";break;
case 13: cout<<"karol ";break;
case 14: cout<<"tuz ";break;
default : cout<<"xato";
}
switch(y)
{
case 1:cout<<"g'isht ";break;
case 2:cout<<"tappan ";break;
case 3:cout<<"qarg'a ";break;
case 4:cout<<"chillik ";break;
default:cout<<"xato";break;

}
}
return 0;
}
Javobi:
4. 100-999 gacha oraliqdagi sonlarni so’zlarda ifodalovchi dastur tuzilsin.
(masalan: 123-“bir yuz yigirma uch”).

Yechish:
#include<iostream>
#include<math.h>
using namespace std;
int main()
{int i,n,s;
cin>>i;
n=i/100;
switch(n)
{case 1: cout<<"bir yuz ";break;
case 2: cout<<"ikki yuz";break;
case 3: cout<<"uch yuz";break;
case 4: cout<<"to’rt yuz";break;
case 5: cout<<"besh yuz";break;
case 6: cout<<"olti yuz";break;
case 7: cout<<"yetti yuz";break;
case 8: cout<<"sakkiz yuz";break;
case 9: cout<<"to’qqiz yuz";break;
default : cout<<"uch xonali son kiriting";
}
n=i/10;
s=n%10;
switch(s){
case 1:cout<<" o’n";break;
case 2:cout<<" yigirma";break;
case 3:cout<<" o’ttiz";break;
case 4:cout<<" qirq";break;
case 5:cout<<" ellik";break;
case 6:cout<<" oltmish";break;
case 7:cout<<" yetmish";break;
case 8:cout<<" sakson";break;

case 9:cout<<" to’qson";break;

switch(i)
{case 1:cout<<" bir";break;
case 2:cout<<" ikki";break;
case 3:cout<<" uch";break;
case 4:cout<<" to’rt";break;
case 5:cout<<" besh";break;
case 6:cout<<" olti";break;
case 7:cout<<" yetti";break;
case 8:cout<<" sakkiz";break;
case 9:cout<<" to’qqiz";break;
}
return 0;}
Javobi:

5. Yoshli yillarda aniqlovchi 20-69 gacha butun son berilgan. Son kiritilganda
unga mos so’zlar ifodalovchi dastur tuzilsin. (“yigirma yosh”, “qirq uch yosh”
va h.k.).
Yechish:
#include<iostream>
#include<math.h>
using namespace std;
int main()
{int i,n,s;
cin>>i;
n=i/100;
switch(n)
