Differences Between std::array and std::vector

C++ offers `std::array` and `std::vector` for storing collections. `std::array` is a fixed-size array known at compile time. `std::vector`, on the other hand, can grow dynamically. This makes `std::vector` more flexible for varying data sizes. Here’s a comparison:

“`cpp
#include
#include
#include
using namespace std;
int main() {
array arr = {1, 2, 3};
vector vec = {1, 2, 3};
vec.push_back(4); // Vector size changes
cout << arr.size() << " " << vec.size(); // Outputs 3 4 return 0; } ``` In this code, `std::array` remains fixed while `std::vector` can expand. Choose based on your application needs.
