19/20: Programiranje IT 3

Vežba - Enumeracija

Napisati program koji na osnovu unetog dana prikazuje njegov redni broj.

using System;
namespace Zadatak5
{
 class Program
    {
        enum Dani
        {
            Ponedeljak = 1, Utorak, Sreda, Cetvrtak, Petak, Subota, Nedelja
        };
 
        static void Main(string[] args)
        {
            string dan;
            Console.WriteLine("Unesi dan:");
            dan = Console.ReadLine();
 
            switch (dan)
            {
                case "Ponedeljak":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Ponedeljak));
                    break;
                case "Utorak":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Utorak));
                    break;
                case "Sreda":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Sreda));
                    break;
                case "Cetvrtak":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Cetvrtak));
                    break;
                case "Petak":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Petak));
                    break;
                case "Subota":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Subota));
                    break;
                case "Nedelja":
                    Console.WriteLine("Redni broj dana: " + Convert.ToInt32(Dani.Nedelja));
                    break;
                default:
                    Console.WriteLine("Pogresan unos");
                    break;
            }
        }
    }
}

Niz u C# :

Vežba - Napisati program za invertovanje niza celih n brojeva.

using System;
namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            int n;
            Console.WriteLine("Unesi broj elemenata niza:");
            n = Convert.ToInt32(Console.ReadLine());
 
            int[] niz = new int[n];
            Console.WriteLine("Unesi elemente niza:");
            for (int i = 0; i < n; i++)
                niz[i] = Convert.ToInt32(Console.ReadLine());
 
            int temp;
            for (int i = 0, j = niz.Length - 1; i < niz.Length / 2; i++, j--)
            {
                temp = niz[i];
                niz[i] = niz[j];
                niz[j] = temp;
            }
 
            Console.WriteLine("Niz nakon invertovanja:");
            foreach (int element in niz)
                Console.Write(element + " ");
            Console.WriteLine();
        }
    }
