What does PP do in Ruby?

What is return in Ruby?

Explicit return Ruby provides a keyword that allows the developer to explicitly stop the execution flow of a method and return a specific value. When this instruction is executed the execution flow is suddenly stopped and the ‘return call’ string is returned. So, the puts ‘after return call’ is never executed.

Does Ruby automatically return?

Using “return” is unnecessary if it is the last line to be executed in the method, since Ruby automatically returns the last evaluated expression. You don’t even need that final “mood”, nor do you need those assignments in the IF statement.

What is difference between CP and PP?

Differences Between Cp & Pp The biggest difference between Cp and Pp is how the Standard Deviation is determined. Pp we use sampling and have to calculate an estimated standard deviation of the sample. In Cp we are assuming a stable process and will likely have enough data to calculate a true standard deviation.
