and this approach is taken almost in all operating systems

Windows docs dont talk about this issue

yeah because it isn’t really an issue since it cannot cause any binary exploits because obviously you don’t expect the kernel to give you malicious addresses and your program will crash anyway

Hey if anyone knows any project in c++ that we can do in one month and good for resume plz share

then the behaviour is the same on windows?

well this mentioned almost in any book and paper discussing this scenario basically it would be an stupid approach to bother returning -1 for a program that is going to be killed anyway

Ok, but is a common recomendation to check malloc's return. I don't undenstand why this check is still recommended.

Really nobody do that. Only in debug build in stl functions of when you try to allocate big chunk of memory

your process will be killed only if it consumed more than any other process but sometimes your process isn’t the one that should be killed (probably chrome processes should be killed😂) then they may get killed and in your program mmap() will return -1 and malloc() will return 0 because the operating system had some trouble allocating memory for you at the time also the kernel tries to resolve fragmentation in memory so if you ask for large page than the available clean pages mmap will fail and malloc will return 0 because the empty gaps in your memory is not large enough for the size of the memory page you requested

Of you're deal with large memory allocation in runtime you can check how much free ram available before allocation

then even if I have an address I will not be able to be sure that it is available

Write the code for multiplying two 3*3 binary matrices. _Where the condition for multiplying the two matrices is that the first has a size of (n*m), and the size of the second is (m*h),, and the result is (n*h) ?

Yes

Can you help ?

No, just not interesting. Usual homework for beginners

What does it take to call one a c++ programmer?

Using wch language?

C++

Oooh thought its C, i find it easier

Okay ...do it

but GNU libc dont guarrantee the address returned by malloc

I talking about this line: By default, Linux follows an optimistic memory allocation strategy. This means that when malloc() returns non-NULL there is no guarantee that the memory really is available.

Please I have some questions which I will be glad if I can get the source codes 🙏

Have you learned what the fibonacci series is?

Not yet please

So do some work on it and come back when you have some stuff done. We'll be happy to help with questions then.

I will do some digging into that and get back to u

Thank you

Which school?

How can I rewrite the second 128 bits of a 256-bit data? for first 128 bit slot i use or(and(w,not(0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF)), and(0x0,0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF))
