Node.js + Express.js CRUD API – Todo App Documentation

Create a simple Todo API using Express.js to understand CRUD operations with in-memory data.

Albatta, C dasturlash tilidagi massivlar (arrays) mavzusini senga imtongacha tez va to‘liq tushuntirib beraman. Bu tushuncha testda ham, kod yozishda ham kerak bo‘ladi. Boshladik:
---
✅ 1. Massiv nima?
Massiv (array) — bu bir xil turdagi bir nechta elementlarni bitta nom ostida saqlaydigan ma’lumotlar to‘plami.
---
✅ 2. Massiv qanday e'lon qilinadi?
tip_nomi nomi[miqdori];
Misol:
int sonlar[5]; // 5 ta butun son saqlaydi
---
✅ 3. Massivga qiymat berish
a) Bosqichma-bosqich:
s```onlar[0] = 10;
sonlar[1] = 20;
---
✅ 4. Massiv elementiga murojaat qilish
---
✅ 5. For sikli bilan massivni o‘qish
---
✅ 6. Foydalanuvchidan massivga qiymat kiritish
---
✅ 7. Belgilar (char) massivi — string
---
✅ 8. Massiv o‘lchami — sizeof
---
✅ 9. 2 o‘lchovli massiv (matritsa)
---
✅ 10. Massivni funktsiyaga uzatish
---
📌 Muhim savollar uchun tayyor bo‘l:
1. Massivdagi birinchi elementga qanday murojaat qilinadi? → a[0]
2. Massivdagi oxirgi element? → a[n-1]
3. Indeks tashqarisiga chiqilsa? → Undefined behavior (xatolik!)
4. String nima? → Belgilar massivi (char[])
5. C tilida massiv uzunligi o‘zgaradimi? → Yo‘q, statik (oldindan belgilanadi)
---
Agar xohlasang, test savollariga o‘xshatib 5–10 ta mini imtihon tuzib ham beraman. Shunchaki ayt 😊
Omad bo‘lsin! 🙌

✅ 3. Massivga qiymat berish
a) Bosqichma-bosqich:
s```onlar[0] = 10;
sonlar[1] = 20;
b) To‘liq boshlash:
```int sonlar[5] = {10, 20, 30, 40, 50};
---
✅ 4. Massiv elementiga murojaat qilish
printf("%d", sonlar[2]); // 30 ni chiqaradi
> Eslatma: C tilida indekslash 0 dan boshlanadi. Ya’ni sonlar[0] — birinchi element.---
✅ 5. For sikli bilan massivni o‘qish
for (int i = 0; i < 5; i++) {
printf("%d ", sonlar[i]);
}---
✅ 6. Foydalanuvchidan massivga qiymat kiritish
int a[5];
for (int i = 0; i < 5; i++) {
scanf("%d", &a[i]);
}
---
✅ 7. Belgilar (char) massivi — string
char ism[10] = "Ali";
printf("%s", ism); // Natija: Ali
> Belgilar massivi satrni ifodalaydi. U \0 bilan tugaydi.
---
✅ 8. Massiv o‘lchami — sizeof
int sonlar[5];
int uzunlik = sizeof(sonlar) / sizeof(sonlar[0]);
---
✅ 9. 2 o‘lchovli massiv (matritsa)
int m[2][3] = {
{1, 2, 3},
{4, 5, 6}
};
printf("%d", m[1][2]); // 6---
✅ 10. Massivni funktsiyaga uzatish
void chiqar(int a[], int n) {
for (int i = 0; i < n; i++)
printf("%d ", a[i]);
}---
