passing dynamic string array

[jk237]

I want to be able to dynamically create an array of strings. For example, I might want to create an array of state names. The number of states and string length are unknown until runtime. I'm aware I could accomplish this with a vector, but want to learn the c-like way of doing the same thing.

void CreateNames(char ** names)
{
  *(names++) = "Maryland";
}

If this could work, how could I pass a pointer to this method?

I was able to do something similar in this manner.

 char* arr[25];
CreateNames(&arr[0]);

But here I'm specifying the length of the string to be 25, right?

No.

char* arr[25];
This creates an array of 25 char-pointers. Each of these 25 char-pointers is going to point to a string. You've limited yourself to 25 strings, but you've said nothing about the length of those strings.

Thanks,

Let's take this a step further. I do not want to specify a fixed size for the number of char pointers I create. This will be determined at runtime. Can I do this?

Just wondering, why not use a vector instead? Or do you want to learn dynamic arrays specifically?

I'm trying to learn about dynamic arrays. I just don't want to initialize the array with a fixed size. I want the method to to be flexible enough that I don't have to hard code limits, etc.

Ok, here is a tutorial for dynamic arrays, I benefited from it in the past:
