Question: What is the meaning of the two parts specified between parentheses in a range-based for loop, separated by a colon?
- The first is a variable declaration that will hold an element in a sequence. The second is the sequence to traverse.
- The first is an iterator, and the second is the increment value to be added to the iterator.
- The first is the iterating variable. The second is an `std::pair` that specifies the range (start and end) in which the variable will iterate.
- The first is a container object. The second is an `std::pair` that specifies the range (start and end) in which the elements will be accessed within the loop.
Answer: The correct answer of the above question is Option A:The first is a variable declaration that will hold an element in a sequence. The second is the sequence to traverse.
