1. Comments C++ programming: Proof gram comments allow the programmer to document information about the program. the compiler basically ignores these comments, and they have little impact on how a program functions. why, then, are program comments important? what things might we consider commenting in a program?

2. Data Types: C++ is a typed programming language. it requires a programmer to specify the data type of a variable before that variable may be used to store data. why does the compiler need to know what type of data will be stored in a variable before it can allocate space to it?
