The video tutorial explores the STL string class, focusing on iteration, comparison, and string manipulation. It begins with setting up a project and creating a function to count vowels in a string. The tutorial then tests the function, explaining iterators and pointer logic. It covers comparing and sorting strings alphabetically using the swap method. Finally, it explores various string class methods, demonstrating how to access them through header files and tool tips.
