Ruby If Or Condition

The if block statement is executed if condition is true otherwise else block statement is executed.

Ruby if or condition.

Executes code if the conditional is true. If var 10 print variable is 10 end. Here s the key difference between ruby and most other languages. And and or originate like so much of ruby in perl.

Ruby if else statement tests the condition. A b is 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.

The values false and nil are false and everything else are true. These if experssions essentially check whether a condition is true or not. If expressions are used for conditional execution. The ruby language has a very simple control structure that is easy to read and follow.

The conditions are generally of boolean type and return either true or false as the result. And and or are useful operators. A common perl idiom is. 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. If else if syntax. This is what needs to be true for the code inside the condition to work. 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. Notice ruby uses elsif not else if nor elif. In perl they were largely used to modify control flow similar to the if and unless statement modifiers. Checks if the value of two operands are equal or not if values are not equal then condition becomes true.

In ruby you do this using if statements. 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 conditional statements conditional statements are also known by the name of conditional processing or conditional expressions. You just need to understand their special place in ruby programs.
