Nested if-else Statements
Nested if-else Statements
 Should be indented to make the logic clear.
 Nested statement executed only when the branch it
is in is executed. For example, the statement
if (x == 5) {
y = 20;
} else {
if (x > 5) {
y = 10;
} else {
y = 0;
}
}
evaluates the nested if-else only when x is not
equal to 5.
