No you dont, C does implicit type conversions

p1 is just a pointer to the first element in the array.
*(p1+1) would be the second and so on.
*(p1+1) is the same as doing p1[1]
hope this helps

i wouldn't call it array. p1 is a pointer to some block of memory.
arrays as types are different

True

I'm just trying to keep it more simple for @azure prawn

[azure prawn]

its the example from ccpreference

https://en.cppreference.com/w/c/memory/malloc

[wraith sparrow]

void* can be converted to any pointer type.

[narrow sinew]

i'd argue that would hurt them later. i get where you're coming from - but i personally feel that 'arrays are pointers' misconception comes from stuff like these sayings

[azure prawn]

yes.
does it mean if(any numer)f is always true

[wraith sparrow]

?

[soft lintel]

if (x) means if (x != 0)

[azure prawn]

how is this tree entered ? i dont get the condition

[steel hill]

in case of pointers, it checks if the pointer is not a null pointer

[narrow sinew]

if(p1) is the same as if(p1 != NULL)

[wraith sparrow]

yea

[steel hill]

malloc returns a null pointer on failure, so it checks instead of directly using it

after all, the (m)allocation could have failed
