file into array

[babudesai]

how do i read file into array. size of the number in file is not fix, code should be able to read any size of numbers. and i have to make a function to read in file into array.this is what i got so far i forgot how to call fucntion in main file
//functions

void ReadList ( int Array [])
{
ifstream myfile;
myfile.open ( "data.txt");
for (int i=0; i < 100; i++)
{

myfile >> Array [i];

}

myfile.close();

}

void Average ( int Array [], int n, int &Avg, int &Avg_pos, int &Avg_neg)
{
Avg = 0;
Avg_pos = 0;
Avg_neg = 0;
int count_pos = 0;
int count_neg = 0;

for ( int i=0; i < n; i++)
{

Avg += Array [i];

if ( Array [i] < 0)
{
Avg_neg += Array [i];
count_neg++;

}
else
{
Avg_pos += Array [i];
count_pos++;
}
}
Avg = Avg / n;

Avg_pos = Avg_pos / count_pos;
Avg_neg = Avg_neg / count_neg;

}

int Large (int Array[], int N)
{

int big = 0;
for (int i=0 ; i < N ; i++)
{
if ( big < Array [i])
{
big = Array [i];
}
else
big = big;
}

return big;
}


void Display ( int Array [], int N, int Ave, int AveP, int AveN, int Max)
{
for (int i=0; i<N ; i++)
{
cout << Array [i]<< " " ;

}
