1.
Why did we use the condition
amount = balance
and not
amount < balance
in the example for the
if/else
statement?
2.
What is logically wrong with the statement
if (amount <= balance)
newBalance = balance - amount; balance =
newBalance;
and how do you fix it?

5.1: Brace Layout
The compiler doesn't care where you place braces, but we strongly recommend
that you follow a simple rule: Line up
{
and
}
.
if (amount <= balance)
{
double newBalance = balance - amount;
balance = newBalance;
