What tools and libraries have you used in your C++ projects?

In C++ projects, I often used the following tools and libraries:

• STL (Standard Template Library) — standard containers (vector, map, set), algorithms, and iterators.
• Boost — extended libraries for working with threads, smart pointers, regular expressions, etc.
• CMake — build system for project management.
• GTest (Google Test) — framework for unit testing.
• Qt — for GUI development and cross-platform applications.

Example of using STL vector:

#include <vector>
#include <iostream>

int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};
    for (int num : numbers) {
        std::cout << num << " ";
    }
    return 0;
}
