Re: [go-nuts] What are the reasonable reasons to use pointers?

in fact... array indices and fortran's call by address rules make it a pointer language in the sense you mean. when i was a mere boy i had to decode brian kernighan's magical packing of triangular arrays using such a scheme. ;-) On Tue, Jan 1, 2019 at 5:23 PM Drew Derbyshire wrote: > > > On

Re: [go-nuts] What are the reasonable reasons to use pointers?

Most of the answers have been shared already. I'll add only the meaning: Basic variables associate names with the value of data, but pointer variables associate names with the location of data. In an array or slice the name and index serve similar purposes, where the 5 in m[5] is a kind of

Re: [go-nuts] Re: Announcing a Fyne GUI toolkit

Hi, Vulcan looks like an interesting project and could provide an event higher performance rendering for a Fyne driver. Unfortunately support does not seem to be as widespread as OpenGL (and there seem to be some fun driver issues) so my knowledge is currently theoretical. Thanks, Andrew —

Some languages, like Java, don’t have explicit pointer types. But they do it by making almost everything an implicit pointer. Andy > On Jan 1, 2019, at 9:13 AM, Jan Mercl <0xj...@gmail.com> wrote: > > > On Tue, Jan 1, 2019 at 12:34 PM 伊藤和也 > wrote: > > >

[go-nuts] Re: What are the reasonable reasons to use pointers?

What Cris said is one reason. That is, if you need the function being called to be able to change the value, then use a pointer. If you pass a value instead of a pointer, then changes made by the function being called are not visible to the caller. (The situation is more complicated, but that

Re: [go-nuts] What are the reasonable reasons to use pointers?

Pointers are useful to pass around shared state. Values are usually copied so changes on one copy are not visible on the other. Pointers on the other hand are an address to some value (and the address is also copied by passing it around) but the value these addresses point to is exactly one same
