How to write a undertemined size array to a txt file?

[TheSeven]

Hey guys, I'm doing a Text-based RPG game and it will include some checkpoints, on those checkpoints the game will save the progress, so I need to write all my variables to a text file and then read them all when the player loads the game.

Some of my variables, like enemyNames, dont have any determined size, they're like this: "int enemyNames[];"

So how do I write an array to a text file without determining a size?
And how do I read them when the player loads the game?

Thank you so much for your help.

¿how do you use it, if you don't know its size?

You need to give those arrays sizes. Just give them a size definitely larger than you are going to use. I also wonder, why are you giving your enemies integers for names?

it's just for the names and stuff like that, it's undertemined so i can add more names without having to change its size each time but, as i've seen here and in other forums, i need to definitely give them size...
as for the int for names, i was distracted, it's string ofc

i still don't know how to read the data from the text file and give those values to the differente variables, can anyone give me a hint?

Read about the standard library containers, such as std::vector.
