EULERS_NUMBER_APPROXIMATION
The C++ program featured in this tutorial web page generates an approximation of the the mathematical constant named e (i.e. Euler’s Number). The program user is prompted to enter a nonnegative integer to store in a variable named N. Then the approximate value of e is computed by adding N unique terms (and each of those N terms is 1 divided by factorial i (and i is a nonnegative integer which is smaller than or equal to (N – 1))). Note that the actual value of e is a limit which cannot be determined using a finite number of additions as described in the previous sentence. Instead, the actual value of e is defined as the sum of every unique instance of (1/(i!)) such that i is a nonnegative integer.

Let E be 0. Let N be a nonnegative integer. For each nonnegative integer i (starting with 0 and ending with (N - i)): Add (1/(i!)) to E. End For. // E represents the approximate value of Euler's Number. // As N approaches INFINITY, E approaches Euler's Number.

PROGRAM_COMPILATION_AND_EXECUTION
STEP_0: Copy and paste the C++ source code into a new text editor document and save that document as the following file name:
eulers_number_approximation.cpp
STEP_1: Open a Unix command line terminal application and set the current directory to wherever the C++ is located on the local machine (e.g. Desktop).
cd Desktop
STEP_2: Compile the C++ file into machine-executable instructions (i.e. object file) and then into an executable piece of software named app using the following command:
g++ eulers_number_approximation.cpp -o app
STEP_3: If the program compilation command does not work, then use the following commands (in top-down order) to install the C/C++ compiler (which is part of the GNU Compiler Collection (GCC)):
sudo apt install build-essential
sudo apt-get install g++
STEP_4: After running the g++ command, run the executable file using the following command:
./app
STEP_5: Once the application is running, the following prompt will appear:
Enter a nonnegative integer which is no larger than 65:
STEP_6: Enter a value for N using the keyboard.
STEP_7: Observe program results on the command line terminal and in the output file.
