3. C# dasturlash tilida Saralash va izlash algoritmlariga doir dasturlar tuzish. using System;

//bubble sortda saralash

class Program

2-Mavzu. Dasturlashda kutubxonalardan foydalanish: ro‘yxat, stek, navbat, daraxt, rekursiv protseduralar.

To‘g‘ri burchakli uchburchakning katetlari berilgan uning gipotenuzasi va yuzasini toppish dasturi topilsin.

public static void Main()

{

double a, b, c, P;

Console.Write("a=");

a=double.Parse(Console.ReadLine());

Console.Write("b=");

b=double.Parse(Console.ReadLine());

c=Math.Sqrt(a*a)+(b*b);

P=a+b+c;

Console.Write("c=" +c +"

P=" +P);

Console.ReadKey();

}

Uch xonali son kiritganda natijasi shu uch xonali sonning teskarisini chiqarish dasturi tuzilsin.

public static void Main()

{

int a, b, c;

Console.Write("3 xonali sonni kiriting:");

a=Convert.ToInt32(Console.ReadLine());

b=a%10;

a=a/10;

c=a%10;

a=a/10;

Console.Write(+b +" " +c +" " +a);

Console.ReadKey();
