Initialize char **

[rasika]

I have a structure
typedef struct m
{
char *name,
char **alais;
}mystruct;

The way I have initialised name field of the struct i want to intialise
the alais field to { "geeta", NULL } char array .
So how do i Do it?

mystruct a={
name:"myname",
};

Not sure I understand you, but any string in your code is null terminated,
i.e.

char *t="yourname";

t actually points to a null terminated string, so you already have a null
there.

mystruct a={
.name= "myname",
.alais= (char *[]) { "Geeta", "Seeta", NULL }
/* I would want to know if this casting is correct! */
};

int

printf ( "Name: %s\n", a.name );

Name: myname
Alais:
Name: Geeta
