using namespace std;

int main()

{

int n, i;

float num[100], sum=0.0, average;

//cout << "Enter the numbers of data: ";

cin >> n;

while (n > 100 || n <= 0)

{

cout << "Error! number should in range of (1 to 100)." << endl;

//cout << "Enter the number again: ";

cin >> n;

}

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

{

//cout << i + 1 << ". Enter number: ";

cin >> num[i];

sum += num[i];

}

average = sum / n;

cout << average;

return 0;
