ITEC 109 Lecture 7 Operations

Review Variables / Methods Functions Assignments –Purpose? –What provides the data? –What stores the data? –What type of variable holds: Hello World

Operations Objectives Other types of variables Operations on variables

Operations Variables The 3 pigs had a big find, 1.5 bars of true gold. String –Text Integer –Whole numbers Float –Decimal places (double in other languages) Boolean –True or false Character

Operations Modify a particular variable Result of: + / - * 2 other variables necessary b=3; c=4; a=b+c; printNow(a); Program

Operations Problem Using JES, calculate how many seconds it takes for… 3 feet20 feetGoing 3 FPS Hint: only use ints if no chance of decimal places!

Operations Homework Celsius to Fahrenheit converter –Ask user for input Testing: Convert 20C to F Experiment: One operation per line, no chaining together F=C*9/5 + 32
