iterate vector c++ using algorithm code example

Example 1: c++ iterate through vectgor

std::vector<int> vec_of_ints(100);
for (int i = 0; i < vec_of_ints.size(); i++){
 	std::cout << vec_of_ints.at(i) << " "; 
}
std::cout << std::endl;

Example 2: iterate over vector in c++

for (auto & element : vector) {
    element.doSomething ();
}
