Looping through a vector using indices in C++

In some instances, we will want to loop through a vector using indices.

The indices of a vector meals are all the integer values from 0 to meals.size() - 1, so we can iterate over them using an index variable i:

vector<string> meals = {"pancakes", "pasta", "pizza", "avocado"};

for (int i = 0; i < meals.size(); i++) {
	cout << "Meal number " << (i + 1) << " is " << meals[i] << ".\n";
}

The output of this code is:

Meal number 1 is pancakes.
Meal number 2 is pasta.
Meal number 3 is pizza.
Meal number 4 is avocado.

Assignment
