you know... std::string is nothing but a char array wrapped in a class

But in : char *a[ ] ={ "hello", "world"} ; char **b =a; Here **b is a pointer to a pointer, which is *a, to a character, and **a is simply the first char of *a. Correct?

which is *a » ? I meant that the pointer **b points to is *a, the first element of array a

Have you tried running and experimenting with the code? This coul answer so many qeustions

then no. **b is no pointer

So what's its name

char ? Since you dereference it twice

Name of **b

So what's the diffrence between a char and char**

So what's the diffrence between a char and char**

a char** is a pointer to a pointer to char char is a simple character char could be e.g. 'a' or 'b' char** could be any memory address such as 0x653223A0

The diffrence is in their functionality, we can access diffrent elements of a string constant through a char** variable, but a char just contains a char variable?

But in : char *a[ ] ={ "hello", "world"} ; char **b =a; Here **b is a pointer to a pointer, which is *a, to a character, and **a is simply the first char of *a. Correct?

Here the pointer **b points to is *a, correct?

no - **b is still no pointer b and *b are pointers

It's a pointer to a pointer to character

so if **b is a pointer to pointer to character,... what's ***b then? (since you only have two levels of indirection how should you resolve a third one?)

When we declare b as follows: char **b; then b is pointer to pointer to character, besides *b which is a pointer to character is created automatically, true?

then b is pointer to pointer to character » Yes! besides *b which is a pointer to character » Yes! is created automatically » Well, I wouldn't say it's "automatically created". You're just looking at the memory location you're pointer points to and that's what you assign to the pointer. If you have a pointer to pointer to char and look at the memory your pointer points to, then there is a pointer to char ( Ant that shows the issues with pointers. What if it points to 0 or you're not allowed to read the address? )

Ok thanx, I think things are starting to make sense now🌷🌷🌷

sure. But srsly.. try using int instead of char. The string vs char thing might be confusing e.g. int n1[] = { 1, 2 }; int n2[] = { 3, 4 }; int *n[] = { n1, n2 }; int **pi = n; so what is pi ? What is *pi? What's **pi? Which value has **(pi + 1) ?

Is it ok to developer an app in c++ when Java is much easier?

Many times, pointers are so confusing

Which is the best Ide to use c++

Visual Studio is a great IDE. If you are not running Windows you can give Eclipse a try or use editors such as Visual Studio Code

Yeah, a great ram eater, yummy 😂

Sure, but most IDEs are.. At least Visual Studio has so many features. Even Visual Studio Code consumes tons of memory..
