Your stack currently stores only single characters.  I think you want
to store strings instead, is that right?

If you are willing to live with a pre-determined max. string length
then you could use the following stack definition.

#define MAX_LEN	1000
#define MAX_STRING 20;

typedef struct stack {
	char s[MAX_LEN][MAX_STRING];
	int  top;
} stack;

or if you wouldn't to be more adventurous and do your own dynamic
string allocation, you could just store pointers to strings, allocate
space on push and free it on pop.

typedef struct stack {
	char *s[MAX_LEN];
	int  top;
} stack;
