Style Guide

When using binary operators, you should leave at least 1 space between the operands (the things being operated on) and the operator. When using a unary operator, you should not leave any space. Remember, you should follow style conventions to help code be readable to humans.

Good style:

a += 1;
a = 5 - 1;
a++;

Bad style:

a+=1
a=5 -1;
a   ++;

Lots of Operators!

Now that you’ve learned all of these operators, you might be tempted to do something like this:

a += b++ * --a % 50;

However, as you probably can see, this is not very readable. Therefore, if you have a lot of operators, you probably want to separate them into multiple lines.
