assembler preprocessor feature, you can define names like R0, but it's a good idea to learn to use APCS names when you're modifying code written by someone else. Register name Reg # APCS Significance R0 A1 Work Register R1 A2 " R2 A3 " R3 A4 " R4 V1 Must protect R5 V2 " R6 V3 " R7 V4 " R8 V5

Singleton mode The thing to do is simply to ensure that an object is globally unique.Is that right? To see the standardSingleton mode (Singleton pattern): Ensures that a class has only one instance, and instantiates itself and provides this instance to the system as a whole.This class is called a singleton class, and it provides a method for global access. Singleton mode is an object-creation pattern.It seems that I didn't define it all right.The first guarantee class has only one instanceThe se
