pointers

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?

The following is 2 different definitions of the problem: How can I process 2 arrays so that I can keep the data of duplicate array[key] values. I have arrays A and B. I want to create array C with the children that their id/key values exist in both A and B arrays. Thank you >>> More

I'm going through a Fortran code, and one bit has me a little puzzled. There is a subroutine, say SUBROUTINE SSUB(X,...) REAL*8 X(0:N1,1:N2,0:N3-1),... ... RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
