If-Statements and If/Else Statements Using Conditionals to make decisions

REVIEW OF LOOPS! What is the best way for Karel to move 10 times? move(); move(); move(); move(); move(); move(); move(); move(); move(); move(); B. for (var i = 0; i < 10; i++) { move(); } C. move(10); D. move10();

What does this For loop mean? for (var i = 0; i < 10; i++) { move(); } “Var i” refers to everything inside the curly brackets, so when it says “i <10; I++” it is actually saying that it will call “var i”, add one number to it, and then follow the loop again UNTIL it is equal to or greater than 10.

When to use If-Statements If statements have a specific purpose, just like functions and loops. Statements help the computer prevent errors by calculating a decision based on the rules it has created. When would we use something called an “If/Else-Statement”?

If/Else Statements If/Else statements are used when you need the computer to make more complex responses to decisions, meaning that it is dealing with multiple true or false problems
