With an if statement, a condition must be true for the code within to execute.
If(input = 1)
Print "true"
Else
Print "false"
In the above code, when the input becomes 1 the code will print 'true'. It will only ever do this when the input is 1 so if it changes to any other number it prints false. This works even if we remove the else statment
If statements are normally used for true/false decisions, they're very similar to switch statements in the way that they work. The only difference between the 2 is their syntax.
Else statements can be used if specific code should execute if the condition wasn't met. In the above, if input isn't 1 then it will print false. If you don't include an else statement then the program will evaluate the condition, execute the code if it needs to and then move onto executing the remainder.
