Hello! I want to know how an array of strings is declared? What I do is I declare an array of pointers of pointers to strings. Eg.
char *array[]= {"string1","string2","string3"};
I was reading about modifying environment variables in Linux and stumbled upon the pointer char **environ ( http://www.cs.bham.ac.uk/resources/courses/2005/17423/doc/libc/Environment-Access.html#Environment-Access ).
char **environ is declared as an array of strings. I think it should be a pointer to a pointer. For eg.
char *array[]= {"string1","string2","string3"};
environ = array;
Am I doing something wrong?
I also read somewhere that char *argv[] = char **argv.
How is it possible?
