need help with functions (beginner level)

[red pollen]

so i know void is used for not returning a value

but what does the second function mean

and should it be

int instructions(int option)
```?

my goal is to make the user answer with a listed number (1 - 3), and then return the integer they input back to the main program to be used in an if statement depending on the value

if anyone reaches out to me, please @ me, thanks 🙏

the int means the return type must be int

for instance, you've got there a string return value, return it

cin is asking for user's input, it writes into option, its type is int

so basically, u need to convert that int into string

and return it

@red pollen

ofc the most optimal variation would be to return an int, no need for string if u wish to have a number returned
