FORTRAN PROGRAM FOR MEANS (Beginner)

[rk2ray]

I am learning Fortran and I am able to write code for 3 number means. Now For computing it for set of numbers is not getting in my mind. I am not able to do it.

Writing a single Fortran program that calculates the arithmetic mean, rms (root-mean-square) average, geometric mean, and harmonic mean for a set of numbers. Running the code for the following four sets of numbers.
(a) 4, 4, 4, 4, 4, 4, 4
(b) 4, 3, 4, 5, 4, 3, 5
(c) 4, 1, 4, 7, 4, 1, 7
(d) 1, 2, 3, 4, 5, 6, 7

Thanks for the help.

Can you post what you have done so far?

Is this the same program that you're discussing in your other thread?

You've already programmed the formulas. Are you having trouble doing the arithmetic?

I understand that learning a new programming language can be challenging, especially when it comes to more complex tasks such as computing means for a set of numbers. However, with practice and dedication, I am confident that you will be able to successfully write a Fortran program that can calculate means for any given set of numbers.

To start, I recommend breaking down the problem into smaller steps and tackling them one at a time. First, try writing a code that calculates the arithmetic mean for a set of numbers. Once you have that working, you can move on to adding in calculations for the other types of means (rms, geometric, and harmonic).

It may also be helpful to do some research and look for examples of similar programs written in Fortran. This can give you a better understanding of how to structure your code and what functions or commands to use.

Additionally, practicing with different sets of numbers, such as the ones provided in the prompt, will help you test and improve your code. Don't be afraid to make mistakes and learn from them.

Overall, keep at it and don't get discouraged. With persistence and effort, you will be able to successfully write a Fortran program for means. Best of luck!
