A have a string, called "joshs_diary", that is huge (there was a lot of drama in middle school). But I don't want every one to k
now that this string is my diary. However, I also don't want to make copies of it (because my computer doesn't have enough memory). Which of the following lines will let me access this string via a new name, but without making any copies? a. std::string book = joshs_diary;
b. std::string & book = joshs_diary; const
c. std::string * book = &joshs_diary;
d. std::string book(joshs_diary);
e. const std::string & book = joshs_diary;
f. const std::string * const book = &joshs_diary;
g. std::string * book = &joshs_diary;
In C language, the asterisks, ' * ', and the ampersand, ' & ', are used to create pointers and references to pointers respectively. The asterisks are used with unique identifiers to declare a pointer to a variable location in memory, while the ampersand is always placed before a variable name as an r_value to the pointer declared.
