Any help is appreciated, thank you!

What are the arguments for and against representing Boolean values as single bits in memory. (Recall that the C++ bool type is actually one byte in size despite the fact that a logical true/false can be encoded in one bit.) Describe the functions performed by a garbage collector. What are the advantages and disadvantages of using a programming language with garbage collection services? Recall that many programming languages use short circuit evaluation when determining the result of a complex boolean expression involving add/or operations. What are the benefit of using short circuit evaluations? Are there are safety/reliability issues involved? If so, what are they? Describe how the following programming languages deal with the dangling else issue: C++, Java, Ruby, and Python. Discuss the differences between name type and structure type equivalence. Explain some potential challenges with implementing structure type equivalence
