When it is best to use pointers instead of references? "reference variable" is the name of the normal variables (like "int i = 10;")?

hello everyone

hi all, I'm trying to step through an integer array using a pointer

problem is I cant seem to figure out the last array pointer

any hints?

thanks, that did the trick

I'm still struggling with the difference between arrays and pointers to arrays (first array elements rather)

there IS a difference, right?

I cant do array++ though, can I

there IS a difference, right?

Of course! For understanding the difference between array name and pointer to the first element in the array, just simply remember this: when and only when the name of an array appears in an expression as an value, it's equal to the pointer to the first element in the array.

the compiler says "++ must be an lvalue"

Also, you might find that, the random access of an array, say array[n], equals to *(array + n) (+ between a pointer and an integer). Hence, n[array] is also accepted.

Of course! For understanding the difference between array name and pointer to the first element in the array, just simply remember this: when and only when the name of an array appears in an expression as an value, it's equal to the pointer to the first element in the array.

hm, but does that help with my array++ example?

Edited: when -> when and only when.

hm, but does that help with my array++ example?

For array++, you treat array as an object, and hence it's not equal to a pointer.

BTW, the same statement holds for the relationship between function and a pointer to the function.

My fault. Here, the term object means a region in memory with type. Of course, arraies are created in C as lvalue. The problem is that, in the use of array++, you first get the value of array, and then apply a self-increment on array. In the last half of behalve, a lvalue is required. However, for array as the name of an C -style array, you could only get the value of it by treating it as a pointer, and in this translation, array(pointer) is an rvalue.

isnt that the definition of lvalue?

https://liam0205.me/2017/02/05/pointer-in-C-and-Cpp/ This is my old blog post of pointer in C and C++. However, Google translation would be applied, if you do not read Chinese.

thanks, I'll check it out

hm, yeah

isnt that the definition of lvalue?

Nope. For me, I could give a informal understanding of C's lvalue and rvalue. lvalue is a named variable, and thus you could get the value of the variable by its name, and you could change the value of the variable by its name (put it on the left of = sign). rvalue is an unnamed variable, and might appear as a temprory variable in the calculation. Hence, getting the value of a rvalue is permitted, but changing the value of a rvalue is not permitted. In the view of memory and of the using of variables, using a variable as lvalue aquire the typed identity of a memory region, and using a variable as rvalue means picking out the value stored in a typed memory region. Hope this helps.

(In C++, there are also xvalue, gvalue, glvalue, etc. Well, the awful C++.)

yes, I see

both are typed and both are regions in the memory, right

here's what k&r have to say regarding the array vs &array problem I had: "There is one difference between an array name and a pointer that must be kept in mind. A pointer is a variable [...]. But an array name is not a variable; constructions like [...] a++ are illegal."

on second thought, that doesnt exactly help either, does it

but it doesnt 😞

Hi you al

All

https://gist.github.com/Liam0205/8e206c87677accfc65aa4291d9f49b6d Today's toy.

do any of you have experience with using git from visual studio?

from what I've seen so far I think I'd rather stick to using git from the command line

whatever you like

sure but it would be easier to "sell" using git to colleagues if it had an easy and intuitive interface from within visual studio

visual studio is capable to use git from out of the box

it does pretty well

I use VS &git every day, it works for me

do you have any best practice guideline or something?

it just works

I have used github desktop / git cmdline / git in VS / git in VSCode, and finally choose command line

relatable

GH desktop and VS doesn't work well with non-Github/VSTS repos

sure but it would be easier to "sell" using git to colleagues if it had an easy and intuitive interface from within visual studio

Why do you have to make them use git? Not using version control in a large and/or collaborative project is plain stupid

Also being afraid of the command line sounds a whole lot like the stereotypical webdevs who use gorillions of frameworks just to have nice animations

But if they insist on no command line, just use VS integration with git or a standalone git application such as sourcetree or gitkraken

yes, probably easier, thanks

Hey if I’m new to coding should I start with C then go to C++ or just jump to C++ I want to start and build a solid foundation for myself just asking I know you all are more skilled ?

jump directly on the c++ train!
