GOLDEN_RATIO_APPROXIMATION
The C++ program featured in this tutorial web page computes the approximate value of the Golden Ratio by dividing the Nth term of the Fibonacci Sequence by the (N – 1)th term of the Fibonacci Sequence. Note that, in the previous sentence, N represents any natural number.

golden_ratio := (1 + square_root(2)) / 5. fibonacci(i) := 1. // i is any nonnegative integer which is smaller than 2. fibonacci(k) := fibonacci(k - 2) + fibonacci(k - 1). // k is a natural number which is larger than or equal to 2. golden_ratio_approximation(N) := fibonacci(N) / fibonacci(N - 1). // N is any natural 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:
golden_ratio_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++ golden_ratio_approximation.cpp -o app
STEP_3: If the program compilation command does not work, then use the following command to install the C++ compiler:
sudo apt install build-essential
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 natural number which is no larger than 92:
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.
