🔤 What is a Char Array?

A char array is a collection of characters, just like a string, but stored in an array format.

cpp
Copy code
char name[10] = "Nikhil";

📌 Important:

• Ends with a null character '\0' to mark the end of string.
• "Nikhil" actually takes 7 characters: N i k h i l \0

✅ Declaring Char Arrays

➤ Method 1: Character by Character

cpp
Copy code
char name[6] = {'N', 'i', 'k', 'h', 'i', 'l'};

🚫 This won’t be treated as a string (no \0 at the end)

➤ Method 2: String Style (Recommended)

cpp
Copy code
char name[] = "Nikhil";

✅ This includes the null character automatically. Memory allocated: 7 bytes.
