Variant № 1
1-masala. F(x)= funksiyaning qiymatini hisoblovchi metod yarating. Delegat yordamida funksiyaning x=10 dagi qiymatini chiqarib beruvchi dastur tuzing.
Masalaning C# dagi matni:
using System;

namespace Mustaqil_ish_2
{
delegate double Funksiya(double x);
class Y
{
public static double natija(double x)
{
return Math.Sqrt(Math.Log(x,3)+x*x);
}
}
class Program
{
public static void Main(string[] args)
{
Console.WriteLine("x ni kiriting:");
double x=double.Parse(Console.ReadLine());
try
{
if(x<=0) throw new Exception();
Funksiya a=new Funksiya(Y.natija);
Console.WriteLine(a(x));
}
catch
{
Console.WriteLine("x noldan katta bo'lishi kerak");
}
Console.ReadKey(true);
}
}
