Formatted IO Quick Guide

Type	Application	Example	Notes
stdio library	library needed to interact with the user through the terminal window and keyboard		This is a preprocessor directive which goes above the main (and under the header comments).
printf	output text to the screen	code in your program file: terminal output when running the executable:	REMINDER! You can use things like field width and precision to format how your output looks when displayed to the screen!
scanf	get input from the keyboard	code in your program file: terminal output when running the executable: FIRST the prompt displays and the program does nothing until the user has entered the right information THEN the program continues execution after the user has hit the Enter key	only conversion specifiers go between the double quotes unless we're trying to skip over blank space when saving a char value see the space before the %c in the example don't forget the & (ampersand) before each variable name CAUTION! nothing is ever displayed to the screen trying to use formatting like field width and precision won't do anything
