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

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

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

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

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

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;

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)

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!

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

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

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

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?

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

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
