Are you saying that the construction
char *p = malloc(sizeof *p);

He said "for n objects of type T"

would allocate enough space to hold the string ""Hello, world!"

Which letter of 'n' were you struggling with?

I generally consider three different malloc situations:

1 "n objects of type T"
T *p = malloc(n * sizeof *p);
T *p = malloc(sizeof *p); /* when n == 1 */

2 string
char *p = malloc(length + 1);
char *p = malloc(sizeof "string_literal");

3 pointer to type void
void *p = malloc(sizeof object_identifier);

p = malloc(sizeof car);
*(struct vehicle *)p = car;

The statement "for n objects of type T" didn't immediately register in
my snoodle. Anyhow after sleeping for 3 hours and re-reading the posts,
the entire thread makes sense.
