Code runs but nothing happens?

When I run nothing shows up and is immediately exited.

Are you using an IDE? If so, which one, and can you use the debugger to trace through and watch what happens (a very powerful tool).

@Alien000,

Have you looked for your output file?

Lab_6_output.txt?

You program doesn't print any output to the console, so there's nothing for it to show you. It would just run, quite and leave that file behind.

[Alien000]

@niccolo it should first ask me to enter rates and balance before sending it to the output file and console does not ask me the questions at all. I tried deleting any file with that name and see if it would start but still doesn't work.

[Niccolo]

@Alien000

Where in the code you think it should ask a question?

There is nothing in the code that prints out a question or statement (I mentioned this already).

There's nothing in the code that takes input from the console.

No use of cout or cin....so....there's no place for it to ask or take keyboard input.

There is a function "input data", but it takes that input from a file.

It doesn't ask you anything.

[Alien000]

I fixed it ROFL TY I'm clueless
