what will be the o/p of this c code? why?

i=printf("hellow"); 
printf("%d",i);

Thanks..

Homework? Anyway, printf returns the number of characters printed. That should help.

---

Output is

hellow6

as printf returns number of characters it has printed...

---

Output will be:

hellow6

Reason:

The first printf will print 6 characters ("hellow"), which will be the return value, assigned to i.

The second printf will print i, which will be 6.

Since there is no NewLine or other separator specified, the two will be run together as hellow6.

---

Assuming that you ran the code and see the output:

hellow6

The explanation is, printf returns the number of characters it was able to write successfully.
