Using Vectors to Collect Data Items
- You must specify which slot you want to use
with the [] operator.
salaries[4] = 35000;
- The number inside the brackets is called an index.
- Because salaries is a vector of double values,
a slot such as salaries[4] can be used just like any
variable of type double.
cout << salaries[4] << "\n";
- In C++, the slots of vectors are numbered
starting at 0.
