## Question 11
**Command:**

By using this command we will be getting the assembly code for the following c program.

---

## Question 12

By using the command cat test.s we will be getting the assembly code for the following c program.

**Observation :**
Assembly code:

.file "test.c"

## Question 13

Yes, we can do optimization. which is done in Question 15.

---

## Question 14

By using this command we will get the ELF file from the assembly file.

***command***

But the problem is we cant able to read that ELF file.So if we want to read the file use the command

By using this command we will get the following observation.
