Mastering C++ STL (Standard Template Library)
The Standard Template Library (STL) provides powerful generic container classes and algorithms such as std::vector, std::map, std::set, and std::algorithm.
cpp Example
#include <iostream>
#include <vector>
#include <map>
int main() {
std::vector<int> numbers = {10, 20, 30};
numbers.push_back(40);
std::map<std::string, int> scores;
scores["Alice"] = 95;
scores["Bob"] = 88;
for (const auto& [name, score] : scores) {
std::cout << name << ": " << score << "\n";
}
return 0;
}
