Because in line 7 you assign to p a pointer to the string "hello", loosing the path to the allocated memory (a memory leak).
Use the strcpy function to assign to the memory pointed by p instead of p itself.(strcpy(p,"hello");)

Additionally, assigning p to NULL doesn't solve all problems as the memory leak is still there. Use strcpy as daniel said.

i don't think this is the case of dangling pointer Programmer Raja , ~ swim ~ shed some light please

Yeah i find why there is no output after spending some time.
It is due to dangling pointer
If we give p=Null
Before we free the memory
It's work's fine

You cant assign the text to 'p' in that manner.
Maybe do sprintf(p, "hello"); or strcpy(p, "hello");

Don't use free(p);
