This is what needs to be true for the code inside the condition to work.
Ruby if or condition.
Here s the key difference between ruby and most other languages.
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.
A b is true.
In ruby you do this using if statements.
If var 10 print variable is 10 end.
If var 10 print variable is 10 else print variable is something else end.
If something is true the condition then you can do something.
You just need to understand their special place in ruby programs.
Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax.
It s important to get it right.
If expressions are used for conditional execution.
These if experssions essentially check whether a condition is true or not.
Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true.
They are used to perform a certain set of instructions if a specified condition is met.
The ruby language has a very simple control structure that is easy to read and follow.
In perl they were largely used to modify control flow similar to the if and unless statement modifiers.
A b is not true.
Ruby conditional statements conditional statements are also known by the name of conditional processing or conditional expressions.
The if block statement is executed if condition is true otherwise else block statement is executed.
And and or originate like so much of ruby in perl.
Checks if the value of two operands are equal or not if values are not equal then condition becomes true.
Ruby if else statement tests the condition.
If else if syntax.
And and or are useful operators.
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.
A common perl idiom is.
The conditions are generally of boolean type and return either true or false as the result.
Executes code if the conditional is true.
