Berilgan matinni gaplarga, so`zlarga ajratish dasturi C#
![Console.Write (I);
Console.Write (0.75<3) ;
Console.Write("Salom”);
Undagi satrga o’zgaruvchi qiymatini qo’shib e‘lon qilish uchun quyidagi kodni
yozish kifoya:
Console.Write("Salom, {0}", I);
Writeline metodining farqi shundaki, u keyingi (yangi) satrdan boshlab
o’ziga yuborilgan o’zgaruvchi qiymatini ekranga chiqarib beradi.
Endi ushbu metodlarga misolni kodini to’liq keltiramiz: using System;
namespace _01_misol
{
class Program
{
static void Main(string[] args)
{
Console.Write(“1-misol”);
Console.ReadKey();
} } }
Bu dastur hozircha hech qanday ish bajarmaydi, u faqat ekranga 1-misol degan
yozuvni chiqaradi.
C# dasturlash tilining alfaviti quyidagilardan iborat .
Alfavit (yoki lite-rallar yig’indisi) C# tilida ASCII kodlar jadvali bilan birgalikda
quyidagi belgilarni o’z ichiga oladi:
- Lotin harflari;
- 0 dan 9 gacha raqamlar;
- “_” belgisi (harf sifatida ham ishlatiladi);

![- maxsus belgilar to’plami : {}, 1 [] + - % / \ ; : ^ ? <> = ! & # ~ *; - boshqa
belgilar.
C# alfaviti so’zlarni tuzishda xizmat qiladi, ya’ni leksemalarni tuzishda.
Leksemalarning 5 turi bor:
- Identifikator
- Kalit so’z
- Amallar belgilari
- Literallar
- Ajratuvchilar
Kalit so`zlar va nomlar.
Quyidagi ro`yhatda C# tilining tiling kalit sozlari va nomlari berilgan.

C# Oddiy satrlar
Oddiy satrlar talqin qilinadigan yangi satr yoki tab belgisi kabi qochish tartibini
o`z ichiga oladi .

Satr elementlari
Satr bu belgilar ketma-ketligidir. Belgilar sarning asosoiy elementlaridir.

C# asturlash tilida satr bilan ishlash metdlari String sinfida joylashgan va bu sinf
satrlarni xavfsiz yaratish, boshqarish va taqqoslash uchun ko`plab metodlarni
taqdim etadi.
Misol uchun:satr uzunligini olish:
String sinfi metodlari:
CompareTo()- berilgan satrni boshqa bir satr bilan solishtiradi va bizga bool
qiymatda javob qaytaradi.
ToLover()- berilgan satrdagi barcha harflarni kichik harflarga o`zgartiradi
ToUpper()- berilgan satrdagi barcha harflari katta harflarga o`zgartiradi
