Ruby If Or Condition

In ruby you do this using if statements.

Ruby if or condition. And and or are useful operators. If var 10 print variable is 10 else print variable is something else end. Here s the key difference between ruby and most other languages. These if experssions essentially check whether a condition is true or not.

The conditions are generally of boolean type and return either true or false as the result. And and or originate like so much of ruby in perl. Executes code if the conditional is true. 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 common perl idiom is. The ruby language has a very simple control structure that is easy to read and follow. A b is not true. Ruby if else statement tests the condition.

Ruby conditional statements conditional statements are also known by the name of conditional processing or conditional expressions. If else if syntax. Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true. Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax.

You just need to understand their special place in ruby programs. They are used to perform a certain set of instructions if a specified condition is met. It s important to get it right. In perl they were largely used to modify control flow similar to the if and unless statement modifiers.

If expressions are used for conditional execution. Checks if the value of two operands are equal or not if values are not equal then condition becomes true. 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. This is what needs to be true for the code inside the condition to work.

Notice ruby uses elsif not else if nor elif. The stock 1 part is what we call a condition. The values false and nil are false and everything else are true. If something is true the condition then you can do something.
