C/C++ :: Simple Shell Argument Parsing

Simple c shell I have been writing. The problem I am having is to do with my argument passing. I have written a simple state machine to parse commands given by the user into an appropriate array of character pointers for use with the function execvp().

My experience with c coding is limited, I think I'm getting confused with pointer manipulation and stack memory. I am trying to store the 'tokens' within my struct->argv[].

Add the ability to handle program names and parameters that contain white space: everything in between two double quote (") characters needs to be treated as one word! E.g. "./hello world" should be treated as the name of one program called hello world (in the current directory, with a space in the middle of the file name) rather than a program called hello with one parameter world.

Here is my parsing functionality.

struct Command {
char *name;
int argc;
char *argv[MAX_ARGS];
};
struct Command command;
void createToken(char *start, char *end)
