Library iostream
We will now see about our first C++ library: the iostream. We will use it to write and read data.
The iostream
To start, we can open the iostream archive. Right at the beginning, we realized two things:
The iostream basically condenses the functionality of two other libraries: istream and ostream.
As expected, being a standard library, the namespace used is the std.
Figure 1
Below, we can see that in this library, eight objects are referenced that can be used for input and output.
Figure 2
In this particular class, we will see the first two: the cout, used for output, and the cin, used for input.
