- Solution

Explore the use of various STL containers such as std::array, std::vector, std::set, and std::unordered_multiset in safety-critical embedded systems programming. Understand how these containers handle data ordering, duplication, and insertion to optimize performance and reliability in resource-limited and safety-focused environments.

We'll cover the following...

Solution

C++
// initializerList.cpp
#include <array>
#include <iostream>
#include <set>
#include <unordered_set>
#include <vector>
int main(){
std::cout << std::endl;
std::array<int, 5> myArray = {-10, 5, 1, 4, 5};
for (auto i: myArray) std::cout << i << " ";
std::cout << "\n\n";
std::vector<int> myVector = {-10, 5, 1, 4, 5};
for (auto i: myVector) std::cout << i << " ";
std::cout << "\n\n";
std::set<int> mySet = {-10, 5, 1, 4, 5};
for (auto i: mySet) std::cout << i << " ";
std::cout << "\n\n";
std::unordered_multiset<int> myUnorderedMultiSet = {-10, 5, 1, 4, 5};
for (auto i: myUnorderedMultiSet) std::cout << i << " ";
std::cout << "\n";
std::cout << std::endl;
}

Explanation

  • In line 11, an std::array, of size 5 and type integers, is created with the given data.
