Method parameters

suggest change

If you want to pass in values to a method when it is called, you use parameters: 

- (int)addInt:(int)intOne toInt:(int)intTwo {
  return intOne + intTwo;
}

The colon (:) separates the parameter from the method name.

The parameter type goes in the parentheses (int).

The parameter name goes after the parameter type.
