Open parens: (
Close parens: )
You often need to use parentheses to group things in code. Here are a few examples of when you use them.
When calling a function, you need to write an open and close parens () after it. e.g. putBall();
When writing an if statement or while loop, you need parentheses to show what is inside it. e.g.
if (condition) {
Remember: if your condition is a function (like in Karel), you need parentheses after that as well. Make sure to include all the parentheses.
if (frontIsClear()) {
Notice how there is the ()) at the end. The first ) ends the ( for frontIsClear and the second ) ends the if statement.
You need parentheses when writing a for loop.
You also use parentheses to group order of operations. e.g.
3 * 4 + 1 // => 13
3 * (4 + 1) // => 15
To type parentheses, hold the SHIFT key and press the 9 or 0 key.
