The ruby language has a very simple control structure that is easy to read and follow. In ruby you do this using if statements. This is what needs to be true for the code inside the condition to work. 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.

If expressions are used for conditional execution. If something is true the condition then you can do something. If var 10 print variable is 10 end. If else if syntax.

Checks if the value of two operands are equal or not if values are not equal then condition becomes true. They are used to perform a certain set of instructions if a specified condition is met.

If var 10 print variable is 10 else print variable is something else end. And and or are useful operators. 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.

The stock 1 part is what we call a condition. Here s the key difference between ruby and most other languages. The conditions are generally of boolean type and return either true or false as the result. You just need to understand their special place in ruby programs.
