Hi i wanna create process and thread by pure C code and dont use windows API or posix standard , can you introduce article(s) about it. Thanks for your help

See:
man 2 clone
It's Linux specific.

You can't. The C standard doesn't deal with processes. So you will have to take help from the underlying OS and the API they provide for doing so which
is what you don't want to use.

#include<iostream>
using namespace std;
int main()
{
int n,i,j;
int arr[]={4,7,9,3,5,6};
int temp=0;
printf("%d",arr[6]);
for( int i=1;i<n;++i){
for ( int j=i+1;j<n;++j){
if(arr[i]<arr[j])
arr[i]=arr[n];
{ temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;}}}
for( int i=1;i<n;++i){printf("%d",arr[i]);}
return 0;
}
Array indexes start from 0 and not 1. arr[6] refers to a non existent element.
In your for loop, i has to start from 0
The value of n is not defined.

Yeah, that's right, but at least they don't want to use POSIX standard API and Windows. So Linux specific will be the answer, lol.
Not sure what is their goal though.
Ammar
Try to open the man page and type
/CONFORMING TO
Ammar
Thanks but linux is under posix :|
So, what exactly do you want?
Can you tell what is your goal?

I don't have exact purpose , may be learning and implementation 🙂

Processes are handled by the OS, so the low level detail of it is OS specific.
man 2 clone is the example for Linux to deal with them.
Ammar
If you don't want to use the libc API wrapper for that clone(2), you can craft your own syscall code for arch specific with inline Assembly in your C code.

What are you are printing on first printf it'll give you garbage value

You can’t you have to use the API and ask the system for permission
Anonymous
Most distributions are POSIX compliant but are not certified because they don’t want to pay the extra fee to get certified
Anonymous
You should use POSIX api to make your applications portable most Linux distributions have extra api features so you can also use this at the risk of portability

I guess you utilized some more than allocated memory for your program👀

Bro when you're doing nums[i]<nums[i+1] in if condition,
And i=n-1, isn't it accessing nums[n] for i+1th index

oh thanks

I don't think he wants to return anything, he wants it to count backward using recursion.

Difference between n— and —n is if you say
print(n—) then it'll send the value of n to the print function and when the function returns it'll decrement the value of n.
if you do print(—n) it'll decrement first then it'll send the value.

you don’t even need sum

Create a program that calculates the cash balance relating to a series of amounts entered cyclically by a user: the entry ends when 0 is typed which acts as a stopper of the sequence.

To be honest having a good theory knowledge alone isn’t enough! In my opinion I’d suggest you to learn c++ from w3schools and try solving problems on platforms like hackerrank/leetcode / codeforces

Practising in the above mentioned platforms can boost your confidence
