Ruby If Or One Line

Here s the key difference between ruby and most other languages.

Ruby if or one line.

With an if statement you can check if something is true. Ruby program that uses one line if statements variable equals 5. If else if syntax. If you don t this right you won t get the expected results.

One equals sign in ruby means assignment make sure to use when you want to find out if two things are the same. Here we will explain all the conditional statements and modifiers available in ruby. Notice that we use two equal symbols to mean equality. Do you use these ruby shorthands.

Ruby offers conditional structures that are pretty common to modern languages. I was sucessful in the following formats. Puts greater than 5 if i 5 puts not greater than 5 if i 5 output not greater than 5. I would like to do something similar to this.

But when you want to check for the opposite not true false. It has the same functionality as an if statement that tests for false not true. I 5 use one line if statements. I m getting into the habit of using these a lot more consistently so i wanted to share.

The ruby language has a very simple control structure that is easy to read and follow. 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. But this syntactic sugar is. I was trying to do a simple one liner while loop in ruby using the curly braces.

This is a negated if statement. If today christmaseve puts santa s on his way end shorthand. If var 10 print variable is 10 else print variable is something else end. These shorthands beautifully consolidate three or more lines of code into one readable line of code.

While x 5 do x 1 end this is sufficient as a one liner but im not a fan of using do end in one liners. 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 expression.
