Ruby If Or Condition

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.

Ruby if or condition.

The if block statement is executed if condition is true otherwise else block statement is executed. Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true. It s important to get it right. Ruby if else statement tests the condition.

The stock 1 part is what we call a condition. In perl they were largely used to modify control flow similar to the if and unless statement modifiers. The values false and nil are false and everything else are true. Notice ruby uses elsif not else if nor elif.

A common perl idiom is. Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax. The conditions are generally of boolean type and return either true or false as the result. The ruby language has a very simple control structure that is easy to read and follow.

You just need to understand their special place in ruby programs. And and or are useful operators. If something is true the condition then you can do something. These if experssions essentially check whether a condition is true or not.

Checks if the value of two operands are equal or not if values are not equal then condition becomes 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. Executes code if the conditional is true. Ruby conditional statements conditional statements are also known by the name of conditional processing or conditional expressions.

If var 10 print variable is 10 else print variable is something else end. If else if syntax. A b is not true. And and or originate like so much of ruby in perl.

This is what needs to be true for the code inside the condition to work. If var 10 print variable is 10 end. A b is true. If expressions are used for conditional execution.
