Introduction to Standard Template Library
Whether you want to sort, filter, or transform a range of data using lists, dynamic arrays, or static arrays, you can accomplish all of this with the STL in just a few lines of code. The STL not only simplifies complex data manipulations but also improves the efficiency of your code. By learning built-in algorithms and data structures, you can focus on solving problems rather than worrying about implementation details.
