Question

I moved my code to use std::vector<char> instead of char *mem = malloc(...) but now I am facing a problem that I can only access the vector data through operator [] but not via a pointer.

I can’t write stuff like:

std::vector<char> data;
fill_data(data);
char *ptr = data;

Before I could do this:

char *data = malloc(100);
fill_data2(data);
char *ptr = data;

Any ideas if it’s still possible to access data in a vector via pointer?

Thanks, Boda Cydo.

Answer 1

The standard way to access the vector data is to use

&data[0]
