Instructions for the exam

You may bring one 8.5” x 11” piece of paper with notes on both sides. This paper will be collected along with your exam, so make your own copy if you would like to keep it.
You may add your notes to this COLLABORATIVE DOCUMENT.
No calculators or phones are allowed in the exam
There are no makeups for this exam
You must write your name on every single sheet of paper including your notes
We will provide you with scratch paper
We will provide you the table of operator precedence
Seating is assigned, updated seating assignments for F18 are at this link: Seating Chart F18
Check the layout of the room

Reference material

You are expected to know the material from the following lectures, labs and homeworks. Please be sure to review the code from lecture which can be found in the lecture notes (different from lecture slides)

Post Midterm material

Link to code written in lecture: https://github.com/ucsb-cs16-f18-mirza/cs16-f18-lectures
Lecture 1 to lecture 8
Homeworks 1 to 4
Labs 0 to 2

Pracice problems:

For topics on lectures 1-8, use the following practice problems. Please solve the problems on your own and don’t just refer to the provided solutions:

We recommend that you try these problems after you have studied/contributed to the collaborative notes (see above) and gone through the labs, homeworks and lectures.

Midterm Study Guide

Write the skeleton of a simple C++ program - see the hello world example covered in lecture
Write code that involves passing parameters to main
Read and write to standard input, output with cin, cout - you should be able to write code that uses these concepts, identify the difference between cout, exit and return
Simple unix commands (covered in labs): cp, mkdir, ls, pwd, cd
An understanding of what compilers are, the compilation and execution process of C++ programs:
- What is g++? What are the inputs and outputs ?
- What is the difference between compiling and running a C++ program?
- How can you ask g++ to use the c++11 libraries when compiling your C++ program
- What are compile-time errors?
- What are run-time errors?
How to pass arguments to main refer to labs that used this concept
While loops, for loops, do while loops (very important)
Functions
- An understanding of how parameters are passed to functions, and how values are returned from a function
- Difference between function that prints to output and function that returns a value
- Function declaration, definition and call
- Writing functions similar to those in the labs
The ability to use variables and basic data types in the type of programs covered in class:
- Identify valid and invalid ways to name variables in C++ - Please refer to book on this
- Identify invalid use of variables: For example using a variable in an expression or assignment before declaring it
- Different ways of initializing variable:
```
      int x =10; int x(10); cin>>x;
```
- Difference between variable declaration and initialization.
- What is the default value given to uninitialized variables in C++ and why this can be a problem
The ability to debug and write code that involves flow control structures taught in class and used in labs. Pay attention to syntax, and the ability to use each appropriately to solve problems similar to those provided in the labs
- If else statements, multiway if-else statements
- For, while and do-while loops, nested for loops (used in lab02)
- Identify the occurrence of infinite loops
Program translation
- Steps (preprocessing, compiling, linking)
- Arguments to g++ (creating objectfiles, differences between object files and executable)
Write a simple Makefile to compile a program that is split between multiple files, or to compile multiple programs
Number conversions: hex, decimal, binary

Past exams

You may also refer to all the past exams. Please note that some questions on these exams may refer to labs that you have not completed so far. You will only be asked questions related to the labs you have completed. The past exams should however provide some information on the expected difficulty and approximate format of the exam. Please note that there may be differences in content as well.
