Python and C++ Comparison

Let's get back to vectors! You have already seen how to declare an empty vector.

In the code below, you can compare Python lists and C++ vector syntax. You'll see that the C++ vector is using a method called push_back, which appends values to the end of a vector. And the line of code

vector<float> myvector (5);

declares vector of size five but without assigning any values. Assigning values to a C++ vector can be a bit tricky; later in this lesson you will see a few different ways to assign values to a vector variable.

The Python code is, as you've seen previously, much shorter to write than the C++ code. However, there are other ways for inputting values in a vector, which you will see in the next section.
