How can I make this function work?

[agamatr]

Ok so I have the function declared at the top before main

void read_data (string firsts [], string lasts [], int ages [], int total);

I also have the function definition at the bottom after main

void read_data (string firsts [], string lasts [], int ages [], int total)
{
	cout << "Enter the number of data items: " << endl;
	cin >> total;
	int i;
	for (i = 0; i<=total; i++)
	{
	cout << "Enter first name, last name, and age: " << endl;
	cin>>firsts[i]>>lasts[i]>>ages[i];
	
	}
}

Then I tried to call the function in main but I don't know how to make it work what I have so far is this

read_data(firsts, lasts, ages, total);

I know I need to declare firsts, lasts, ages and total in main but I don't know how.

what are you trying to accomplish other than making that function run?

[agamatr]

It is a part of a program and I have everything else I just need to know how to call the function in main.. I mean I did call it but I just need to know how to declare firsts, lasts, ages and total so that the function can run properly

[Bdanielz]

can you post all of your code.

You're passing 3 arrays and an integer.
Can you anticipate a maximum size for the arrays?
Not sure why you're passing a value for the total when you're just going to overwrite it in the function. Perhaps you intend to have a variable in main keep the value entered by the user? In this case you'll need to pass total by reference, not value. ie:
void read_data (string firsts [], string lasts [], int ages [], int& total);// note the '&' before total

Adjust the array maxSize accordingly:

const int maxSize = 50;
string firsts[maxSize];
string lasts[maxSize];
int ages[maxSize];
int total = 0;

read_data (firsts, lasts, ages, total);// total will have the value entered in the function.

Thanks it worked this is exactly what I needed to do!
