How to make a process execute two different kinds of code (e.g., some code that computes numbers, other code that interacts with user).

Learning Goal: I’m working on a c programming question and need support to help me learn.Midterm topics:- C code- Manipulate arrays (like integer arrays)- Manipulate strings (character arrays) with string functions, and without functions- Work with argc and argv- Open, read, write, close files- Read input from keyboard- Processes (ch 4 & 5):- Fix broken code that does a fork/exec/wait pattern (perhaps missing some steps)- Explain a zombie is made, and how it is avoided- How to make a process execute two different kinds of code (e.g., some code that computes numbers, other code that interacts with user).- How to run another program (like the shell does)- Answer questions about a process state table like Figure 4.4 in Ch 4 in OSTEP book- Time-sharing, “limited direct execution” (ch 6; stop at page 9):- Explain difference between user mode and kernel mode, and how to switch from user to kernel- Identify which “ring” goes with which mode- Explain purpose of “trap table”, and when it is created and by what (answer: OS)- Explain a figure like 6.2 (ch 6 in OSTEP), ignoring “kernel stack” parts- How process switching works: given a story, explain if it’s a “cooperative” approach or “non-cooperative” approach- Explain how non-cooperative mode worksexam is 40 minutes on Friday 11 am newyork time
