I m getting into the habit of using these a lot more consistently so i wanted to share.

Ruby if then else one line.

If the conditional is not true code specified in the else clause is executed. An if expression s conditional is separated from code by the reserved word then a newline or a semicolon. Notice ruby uses elsif not else if nor elif. X 10 if x 8 puts x is greater than 8 end.

If var 10 print variable is 10 else print variable is something else end. Which is the same as. If a 10 here we used if. All the i o methods are derived from the class io.

You can also add an else expression. The ruby language has a very simple control structure that is easy to read and follow. X 10 if x 8 then puts x is greater than 8 end. All in one line.

H ruby abc rb x is greater than 8. So the whole story is that if a 10 if a is greater than 10 then it will execute puts your number is greater than 10 otherwise it will execute puts your number not greater than 10 end at. If j 0 then if j 100 then. One of the most powerful features present in most programming and scripting languages is the ability to change the flow of the program as certain conditions change.

The values false and nil are false and everything else are true. Is there an alternative. In the first line we are taking input. These shorthands beautifully consolidate three or more lines of code into one readable line of code.

Puts 123 if 2 even. If you have an if else expression there is also a shorthand for that. H ruby abc rb x is greater than 8. The class io provides all the basic methods such as read write gets puts readline getc and printf.

Here s the key difference between ruby and most other languages. The if then else statement in delphi code beginner delphi developers should watch out for if then else traps. It s possible to write an if statement using just one line of code. The simplest form of flow control and logic in ruby is called an if statement or technically speaking in ruby since everything is an expression an if.

Executes code if the conditional is true. This chapter will cover all the basic i o functions available in ruby. If the test expression evaluates to a true then the then expression is evaluated. Puts 123 end this is a shorthand version which can be useful if you have a simple condition.

Ruby provides a whole set of i o related methods implemented in the kernel module. The then is optional. First see a 10 the condition a 10 is comparing a with 10 and if a is greater than 10 then it is true and if smaller then false. If else if syntax.
