passing two different strut member variables as const reference to a function

hibiscusleaves2544 (56)
so far i think i'm on the right track, but i'm having trouble outputting one of the other struct member variables, i'm also not sure if i made the other structure as constant.
I'll post the whole code a bit later in this post, but for now i want to show where i'm having problems.

The struct WeatherMan is being returned back to main, and when i make it's variables constant, it doesn't display.
here's the function that i'm attempting to make WeatherMan variables as constant references

void displayAllData(const DayOfWeek day[], const WeatherMan &getting)
{
	cout << "the name of weatherman is: " << getting.name;
	for (int i = 0; i < 7; i++)
	{
		cout << "The amount of rain for " << day[i].dayName << " is: " << day[i].rainAmount << endl;
	}


and here is the function where i obtain the name of a weatherman and its channel name

WeatherMan getWeatherdata()
{
	WeatherMan data;
	cout << "Please type in your name: "; 
	getline(cin, data.name);
	cout << endl << "Please type in channel name: ";
	getline(cin, data.newChannel);
	return data;
	
}


I also want to know if i passed the DayOfWeek variables correctly, it displays what i want it to display correctly, but the format looks a bit off. i'm not sure if i passed it correctly as a constant reference.


here is the entire code for reference.

	{
		cout << "The amount of rain for " << day[i].dayName << " is: " << day[i].rainAmount << endl;
	}
}

sorry for some of the obscure variables names, i was just testing the waters to see if the code even worked

Look at this snippet:

	WeatherMan obtainingWeather, example;
...
	obtainingWeather=getWeatherdata();
...
	displayAllData(day, example);


You assign information to the obtainingWeather instance but then you try to display example?

Where have you assigned values to the example instance?

i used example for the displayAllData because I wasn't sure if i could use obtainingweather. but now that you pointed that out, I used obtainingWeather to display. my code worked! thank you!

also, am i passing the DayOfWeek variable members correctly to the function displayAllData?

It looks okay. You're passing the array of your day structure which seems to be what you want.
