Hey guys. Here' some baby stuff for you. Any advice as to how this might work will be great.

We're asked to create 2 arrays, size=20, one holds integers and the other doubles. The user enters the values via keyboard. Next, I have to figure out the average for both arrays. I have the headers set for both arrays already, but I'm stuck with the function calls, which need to be in the main. I declared them as

avgA=avg(arr1);
avgB=avg(arr2);

but obviously there's something wrong. I get the 2 errors that say arr1, arr2 are undeclared identifiers. maybe i've just been looking into it so deeply, or maybe it's coz I can't think anymore. =(

Here's the rest of the code:

<lj-cut>
#include <iostream>

using namespace std;

int readData(int[]);
int readData(double[]);
double avg(int[]);
double avg(double[]);

const int SIZE=20;

int main()
{

int a[SIZE];
double b[SIZE], avgA, avgB;

readData(a);
readData(b);

avgA=avg(arr1);
avgB=avg(arr2);

return 0;

}

/********/
int readData(int arr1[SIZE])

{
cout<<"\nEnter a number (integers) "<< SIZE <<" times."<<endl;
for (int i=0; i < SIZE; i++)
{
cin>>arr1[i];
}

return 0;
}

/********/
int readData(double arr2[SIZE])
{
cout<<"\nEnter a number (doubles) " << SIZE <<" times."<<endl;
for (int j=0; j < SIZE; j++)
{
cin>>arr2[j];
}

cout<<endl;

return 0;
}

/********/
double avg(int arr1)
{
return (double)arr1/SIZE;
}

/********/
double avg(double arr2)
{
return (double)arr2/SIZE;
}

</lj-cut>

Thanks so much for any help.
