EE160 - C - What Does A C Program Look Like?

computers are very strict about punctuations and brackets

each line of code is sequentially executed

the main function is the start of our program, analogous to start of a letter

main(){} is how we define a function

function name: main
argument list: (), there are no arguments expected for the main function
function definition: {}, what the function does is defined in the curly brackets
we'll discuss more about functions later

you can call other functions, like printf

including the standard input/output library #include <stdio.h> to gain more functionality

analogous to attachments in letters/emails (something you can refer to and "use" within your letter/program)
read more about the functionalities included with this library at http://en.wikipedia.org/wiki/C_file_input/output

\n tells the computer to output a newline, read more about escaping characters at http://en.wikipedia.org/wiki/Escape_sequences_in_C

white space doesn't matter, but is necessary to allow other humans to read your code

you can add comments to your code to explain what you are trying to do in your code
