The else if Statement
Use the else if
statement to specify a new condition if the first condition is False
.
Syntax
if (condition1) { // block of code to be executed if condition1 is True } else if (condition2) { // block of code to be executed if the condition1 is false and condition2 is True } else { // block of code to be executed if the condition1 is false and condition2 is False }
Example
int time = 22; if (time < 10) { Console.WriteLine("Good morning."); } else if (time < 20) { Console.WriteLine("Good day."); } else { Console.WriteLine("Good evening."); } // Outputs "Good evening."
Example explained
In the example above, time (22) is greater than 10, so the first condition is False
. The next condition, in the else if
statement, is also False
, so we move on to the else
condition since condition1 and condition2 is both False
– and print to the screen “Good evening”.
However, if the time was 14, our program would print “Good day.”
