pointer to unsigned type

[tacit ridge]

if I have a pointer to an unsigned type, does the address need to be unsigned as well? like for example if i did unsigned int* x = 0x.....

do I need the address to be unsigned? or would i be warning free

unsigned int* isn't an int* that is unsigned, it's a * to an unsigned int

and yes, your pointer type needs to match what it's pointing to

[tacit ridge]

ohhh

gotcha i was confused

so the value of * is just a signed int?

or is it an unsigned int

[worn peak]

"the value of *" ??

[tacit ridge]

a pointer is sugned or unsigned?

or does it not matter

[worn peak]

I think technically they're neither, but in practice they're unsigned

what would a negative memory address mean

[tacit ridge]

yea thats why im confused lol

so lets say i define a pointer

and i want to set it to a direct address

do i need to do like 0x....U?

[worn peak]

no

but there are very few reasons to be manually defining an address like that

if you find yourself doing that, take a step back and consider what you're doing

[worn peak]

yeah, "signed" and "unsigned" are only defined in the standard in relation to the integer types, not for pointers

does the address need to be unsigned as well
Have you ever seen a negative address?

[tacit ridge]

So I don’t need the U?

[tacit ridge]

Nope, I’m just confused why I need to use U when I do something like

#define regaddr 0x…..U

[worn peak]

you dont
