Introduction to C++ Standard Template Library (STL)

The C++ Standard Template Library (STL) provides useful components. It includes algorithms, containers, and iterators. STL enhances productivity and code quality. Common containers are `vector`, `list`, and `map`. Here’s an example using `vector`:

“`cpp
#include
#include
using namespace std;
int main() {
vector nums = {1, 2, 3};
nums.push_back(4);
for (int n : nums) cout << n << " "; // Outputs 1 2 3 4 return 0; } ``` In this example, `vector` provides dynamic array functionality. STL simplifies complex programming tasks.
