Ruby if or condition.

The if block statement is executed if condition is true otherwise else block statement is executed. You just need to understand their special place in ruby programs. The stock 1 part is what we call a condition. If expressions are used for conditional execution.

Notice ruby uses elsif not else if nor elif. 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. Executes code if the conditional is true.

And and or are useful operators. In ruby you do this using if statements. And and or originate like so much of ruby in perl. 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.

Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true. If something is true the condition then you can do something.

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. Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax. These if experssions essentially check whether a condition is true or not. They are used to perform a certain set of instructions if a specified condition is met.
