C++ Standard Template Library in Practice - Bidirectional Iterators

The video tutorial explains bidirectional iterators, which allow traversing elements in both directions. It covers their properties, how they differ from forward iterators, and provides a C++ code example demonstrating their use. The tutorial also discusses the efficiency of pre-increment operators over post-increment operators and shows how to traverse a vector backward using bidirectional iterators. Finally, it demonstrates debugging techniques using GDB to analyze code execution.

What are bidirectional iterators and how do they differ from forward iterators?

Explain the requirements that make an iterator bidirectional.

What is the significance of the decrement operator in bidirectional iterators?

How does the use of the pre-increment operator differ from the post-increment operator in the context of iterators?

What does it mean that 'numbers.end()' points to one past the end of the vector?

Describe the process of using a loop to traverse a vector with bidirectional iterators.

What is the output of the loop that multiplies each number in the vector by 10?
