Concatenate string with an integer

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Concatenate the string 'Experiment_ID_' with the integer 'trial_number' to form a unique identifier for the log file. Store this in 'log_filename'.

I'm creating file names for the simulation outputs using 'run_prefix' and 'iteration_count'. Before I generate hundreds of these, make sure the integer is formatted with leading zeros so all the filenames sort correctly when I send them to the data archive team on Monday.

The data logging system just failed because of an invalid filename.
The data logging system just crashed because the filename 'data_run_' combined with 'current_run_number' resulted in an invalid path. I'm trying to create a unique identifier for each simulation run, but sometimes 'current_run_number' is a double, and other times it's an integer, and the file system is picky. I'm afraid of losing data if this happens again. What's the most robust way to combine a string and a number for a filename that always works?

I frequently hit errors when combining strings and numbers for display or logging.
I keep getting type conversion errors or unexpected output when I try to combine descriptive strings with numerical results for plots, reports, or log entries. This slows down my analysis and makes my output look unprofessional to the project manager. What habit should I change to consistently and correctly combine text and numbers for clear, error-free communication of my engineering results?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
