STLport

STLport is a set of pre-written code libraries that implement common programming tools called "Standard Template Libraries" (STL) for C++. It provides ready-made, efficient components like containers (vectors, lists), algorithms (sorting, searching), and iterators, which help programmers write reliable and portable software more quickly. STLport was designed to enable code compatibility across different operating systems and compilers, making it easier for developers to create cross-platform applications. Essentially, it is a reusable toolkit that enhances C++ programming by offering standardized, optimized building blocks.
