Is there something like Jupiter for C/C++

Is there something like Jupyter for C++? Specifically, something that is a long lived process, that keeps its long lived state over this time, and allows me to give it some code, have it JIT compiled, and executed.

Use case: imagine large files in disk and I want to read and parse into memory (imagine this step will take a long time, say tens of minutes), compute some metrics, and generate a plot, but I'm not sure what metrics I want yet, and I would need to iterate on it. Without Jupyter I'm going to have to read and parse the files every time I want to test what some metrics look like. With Jupyter I don't need to read and parse each time, the data is already in memory.
