It s important to get it right.
Ruby if or condition.
A common perl idiom is.
Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true.
And and or originate like so much of ruby in perl.
If var 10 print variable is 10 else print variable is something else end.
The conditions are generally of boolean type and return either true or false as the result.
If else if syntax.
In perl they were largely used to modify control flow similar to the if and unless statement modifiers.
Ruby conditional statements conditional statements are also known by the name of conditional processing or conditional expressions.
If var 10 print variable is 10 end.
The ruby language has a very simple control structure that is easy to read and follow.
Ruby if else statement tests the condition.
You just need to understand their special place in ruby programs.
A b is true.
Executes code if the conditional is true.
Here s the key difference between ruby and most other languages.
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.
Notice ruby uses elsif not else if nor elif.
The if block statement is executed if condition is true otherwise else block statement is executed.
In ruby you do this using if statements.
If something is true the condition then you can do something.
If statement in ruby is used to decide whether a certain statement or block of statements will be executed or not i e if a certain condition is true then a block of statement is executed otherwise not.
These if experssions essentially check whether a condition is true or not.
And and or are useful operators.
Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax.
Checks if the value of two operands are equal or not if values are not equal then condition becomes true.
The values false and nil are false and everything else are true.
The stock 1 part is what we call a condition.
This is what needs to be true for the code inside the condition to work.
