Contracts are removed from C++20 after todays voting.

Jope, but they werent ready yet

Wojciech Razik: True. But we had something. There was a proposal that kind of cuts contracts a little bit: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1607r0.pdf

source?

source?

DM from ISO member. But there will be one more voting on Saturday (I'm not sure how voting process looks like...)

tnx

Contracts are removed from C++20 after todays voting.

What are contracts exactly ? I only know contracts from Solaris/illumos

Can anyone here tell me How to write a c program that read values from user in GUI not on terminal/console? Please share source code if you know.... 🙏🏼

yeah

you make an ui

Tell me how?

you take some answer from SO

and then jam it in your shitty ide

Use something like Qt, GTK or similar.

SO

stackoverflow

Oh!k

I'll try

Thank you so much

Use an UI-designer to create a basic window with an input field, and use that for your program.

Oh!k

I'm not sure about Qt, because afaik it's mainly written in C++, not C.

Thank you so much

its hard tbh

i cant do qt

C program? Oh, maybe opengl?

opengl

good luck lol

Windows gui

just for gui

Windows gui

winforms

hey guys , do you use fuzzers to test your programs?

opengl

That was only for graphics but not for UI, right ?

you can do whatever in opengl

opengl is gpu API

like

talking to gpu

like

That was only for graphics but not for UI, right ?

UI is kind of graphics

take this data

and

display it

And one more question???

This is for next time

Ho

Here what is that value of a that is printed? a is a pointer and it's address is &a but k don't know why that value is printed for "a"

a - random garbage from memory.

a - random garbage from memory.

Memory of what exactly? Pointer a is assigned in the memory If I write &a I ll get where it's assigned but what is just "a"?..It needs to point somewhere and I didn't declare where to.. does "a" hold a garbage value in it?

a holds a garbage value, which gets interpreted to an address, so it's pointing to a random address with a random value in it

Which you likely can't even read

When you write int *a; program allocates space for pointer to int. (on stack) 'Allocates' means "Hey guy, here's address of memory you can use to store your value, but I don't know what's there now. Please initialize it before using if you want reasonable results.". This is &a. a - is random value what's left in this portion of memory from previous usages. For example: a is 8 bytes. Let's assume there was a string "hellowor". Every character in this string - is just a number. 8 number in row combines to one big number. Addresses usually displayed in hex, so we convert our 8-number value to hex representation. And that is what you see on your screenshot.

Of course you can try and dereference it, but I'm pretty sure you will get segmentation fault error. May be it points somewhere, but it's totally random where.

@mmihov @suisei_v Got it! Thanks!

How to make strtok (string tokenizer) (from cstring) work for c++ strings? It works for char str[] = "Hello, world!"; char* p = strtok(str, ', '); // p will point to "Hello" and not for string str = "Hello, world!"

The c in cstring probably refers to the c's strings. That means cpp strings will not work with it

Oh, thank you

I found a way using stringstream

How to delete element from vector?

🌚 .erase(ass);

🌚 .erase(ass);

But it will decrease size of vector, and I don't want to do it

delete without decreas?

call descturtor for 'ass'

delete without decreas?

Yeah

But it will decrease size of vector, and I don't want to do it

If you want to remove an element, but keep the capacity the same, you can either replace it with an arbitrary value, but that won't actually remove it or you can remove it and reserve the capacity the vector had prior to removing it

erase doesn't change capacity

erase call destructor and size--;

But than my vector will contain a garbage
