Demonstrating why string literals (char*) are immutable and how char[] differs,and exploring types of strings based on sizes and their writting style

[Butcher3Years]

char* name = "Cherno";
name[2] = 'a'; // ❌ problem

❌ Why this fails (or crashes / UB)

"Cherno" is a string literal

String literals are stored in read-only memory

char* name just points to that memory

When you try to modify it → undefined behavior

👉 In modern C++, this is actually illegal.

Correct type would be:

const char* name = "Cherno";

Why char[] works
char name[] = "Cherno";
name[2] = 'a'; // ✅ works

✅ What’s different here?

"Cherno" is copied into a writable array

Memory is allocated on the stack

You own the memory → you can modify it
