cpp loop vector code example

Example 1: cpp print vector

for(int i = 0; i < vec.size(); i++)
    std::cout << vec[i] << ' ';

Example 2: c++ iterate over vector

for(auto const& value: a) {
     /* std::cout << value; ... */
}

Example 3: for loop vector

for (auto i = v.begin(); i != v.end(); i++)
    {
        std::cout << *i << endl;
    }
