8. IDEs and Program Basics
We support Xcode and Visual Studio
Detailed installations and project startup instructions on the website
Don’t forget to check out the style guide
eecs183.org/vs
eecs183.org/xcode

9. IDEs and Program Basics
IDEs provide a code editor where you write and edit code
This code is sent to a compiler
The compiler turns your code into object code

10. What is an algorithm? Specific series of steps used to solve a problem
Counting people in a room
Making pasta
Finding a page in a book
Algorithms vary in efficiency and speed
You’ll learn more about this in EECS 203 and 280

11. Which of these are reserved words?
Reminder: reserved words are key words reserved by C++ that have specific meanings and can’t be used as variable names

13. cout and cin cout prints to standard output
You always need to add #include <iostream> at the top of your file when using these!
This allows access to the iostream library which holds the cin and cout operations
cout <<
cin >>
cout prints to standard output
cin reads input from the user

14. Variables
An element in code that has a specific type and holds or stores values
Use descriptive names with these!
Can’t be reserved words
type
name
value
bool isHungry = true;

15. Data Types Type What is it? Examples int Whole number 6, 42 double
Decimal numbers
5.3, 6.0
char
Single character, denoted by single quotes
‘d’, ‘0’, ‘g’, ‘$’
string
Collection of multiple characters, denoted with double quotes
“Go Blue!”, “EECS 183 rox”
bool
Holds values true and false
false (0), true (1 and any other non-zero number)

16. Sample Program #include <iostream> #include <string>
using namespace std;
int main (){
cout << “Enter your name: “ << endl;
string users_name;
cin >> users_name;
cout << “Hello “ << users_name << “!”;
cout << endl;
return 0; }
Output: Enter your name: Katherine
Hello Katherine!

17. Operations and Operators
/ % * =
-order of operations applies

18. Operations with different types
Types matter in operations!
Dividing an integer by an integer results in an integer
3 / 2 = 1
The result is truncated down
Dividing an integer by a double or vice versa results in a double
3 / 2.0 = 1.5
6.8 / 2 = 3.4

19. Modulus Operator % This operator gives you the remainder of a division
5 % 2 = 1

20. Modulus Operator % This operator gives you the remainder of a division
5 % 2 = 1
Think about how many times the second number goes into the first
2 % 5?

21. Modulus Operator % This operator gives you the remainder of a division
5 % 2 = 1
Think about how many times the second number goes into the first
2 % 5? 2!
Since 2 does not go into 5 at all, you’re left with the original number

24. Tips for Success Post on Piazza Start early (the CS mantra)
Plan before you code
Work with friends
Use whiteboards
Don’t stress! You’ll do great
