Lesson 10

STL and Modern C++ Basics

Modern C++ includes powerful library tools such as the Standard Template Library. A great place to start is vector and the range-based for loop.

vector Example

Example

#include <iostream>
#include <vector>
using namespace std;

int main()
{
    vector<int> numbers = {1, 2, 3, 4, 5};

    for (int n : numbers)
    {
        cout << n << " ";
    }

    return 0;
}

auto Example

Example

#include <iostream>
using namespace std;

int main()
{
    auto x = 10;
    auto y = 3.14;

    cout << x << endl;
    cout << y << endl;

    return 0;
}
