Why is my char* writable and sometimes read only in C++

Question

I have had really big problems understand the char* lately. Let\'s say I made a recursive function to revert a char* but depending on how I initial

Answer 1

char * bob = "hello"; 

This actually translated to:

const char __hello[] = "hello";
char * bob = (char*) __hello;

You can't change it, because if you'd written:

char * bob = "hello"; 
char * sam = "hello"; 

It could be translated to:

const char __hello[] = "hello";
char * bob = (char*) __hello;
char * sam = (char*) __hello;

now, when you write:

char * bob = new char[6];    
bob = "hello\0";

First you assign one value to bob, then you assign a new value to it. What you really want to do here is:

char * bob = new char[6];    
strcpy(bob, "hello");
