If you code in C++ or any modern day language, your code is translated into binary.

But how do you get access to those binary codes?

How do you install your own software in your own custom computer?

For instance, lets say I wanted to create my own calculator. I got all the components I need and put them together. Then I have to put own my software that communicates with all the components and does basic arithmetic operations. How do I install my own software? How do I get my drivers to communicate to the hardware components?

How do I apply my software engineering skills into created my own software for my own computer rather then creating my own software for a windows machine?

It's not exactly clear what you're asking, but I assume that you want to know how operating systems work.

Check out this and this. It might also help if you see Intel's developer manuals for reference.

Thanks for your response, let me reword my question.

When I create my own custom computer, I want to install my own software. For instance, in the computers we're running right now the majority of us have Windows installed.

My question is how do we install our own softwares coded in C++ for instance inside our small custom computers.

I've been thinking about making my own calculator for testing purposes.

You put your code one way or another on a memory storage (rom/eprom/flash) and when the cpu gets power it reads and executes that code

Anyhow, a little thing i play with sometimes that does this:

You can program it, and after that each time it gets enough power it will execute your code
For a calculator i recommend getting a little lcd panel and a way to input data.
