Guys, please explain why the values in memory in this program change. The program returns 20 2109490, instead of 20 20
#include <stdio.h>
#include <stdlib.h>
int main()
{
int num, *arr, i, buf, buf2;
num = 7;
arr = (int*) malloc(num * sizeof(int));
for(i = 0; i < num; i++) {
*(arr + i * sizeof(int)) = 20;
}
buf = (int)(*(arr + 12));
printf("%d ", buf);
buf2 = (int)(*(arr + 12));
printf("%d ", buf2);
return 0;
}

you are moving pointer offset
Dima
so it reads some garbage

Hello, I just completed a course in DS and algo and I am interested in building softwares using C++, what should I do next?

practice, start your own projects

Here is the problem, I dont know how to transition from console based projects to actual functional projects

I know it

Hey guys, it seems that I often fall into a bad pattern that results in circular dependency issues. This is related to templated methods. I'll provide below a sample of the stated pattern. If someone has experience in how to avoid this, I'll be grateful :)

Oh sorry

No worries!

There's probably a better design, but I faced a similar problem a while ago and ended up changing the design

Generally it' s not a problem since we can move the complete type inclusion in a cpp file. But when I need to use both the templated parameter and the complete A type, I end up with this. It's very limiting

I hope that c++ modules will improve this situation :) https://www.modernescpp.com/index.php/c-20-modules

Hey guys I learnt C now suggests me a project to practice
klimi
then make a ....

almost sure that circular dependencies will be forbidden in modules
klimi
hm then you can make a program to help people write with all ten fingers
Hugo

Yeah it will. But it will be easier to scope what to import without having to over-split the header files.

klimi
bye
klimi
normal project
Sasuke
You mean something which teaches how to type?
klimi
yes
Sasuke
Gui can do that job better I guess
Mity
That's the basic thing
klimi
sure
klimi
i have done that before
klimi
its not hard
Mity
Go to hacker rank or some thing and solve algorithm
Mity
Using c
klimi
the my os? i can't i formated harddrive xD
klimi
one tty you could say
klimi
but actually its not as that hard to go to basic vga graphics
Mity
I'm also learning shell😅

I did but small projects are more interesting
