Question

make a c ++ program ethat calculate the sum ,mean of series numbers

Answer 1

 #include <iostream>
using namespace std;


int main()
{
    int i, n, sum = 0, mean=0;
    cout << "\n\n Find the sum of the series (1*1) + (2*2) + (3*3) + (4*4) + (5*5) + ... + (n*n):\n";
    cout << "------------------------------------------------------------------------------------\n";
    cout << " Input the value for nth term: ";
    cin >> n;


    for (i = 1; i <= n; i++) 
	{
        sum += i * i;
        cout << i << "*" << i << " = " << i * i << endl;
    }
    cout << " The sum of the above series is: " << sum << endl;
    
    for (i = 1; i<= n; i++)
    {
        mean = sum/n;
        cout << sum << "/" << n << " = " << sum/n << endl;
        
    }
    
    cout << " The Mean of the above series is: " << mean << endl;
}
