Can u help solve this problem in c++?
Make a program in C ++ to calculate the quadratic mean of n values entered by the user. The quadratic mean is given by the following equation:

The program should read the value of n and the n values of x.
What's wrong with my code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int n;
int x;
int soma;
double xq;
cout << "Digite o valor de n: ";
cin >> n;
soma = 0;
for(int i = 0; i < n; i++){
cout << "Digite o valor de x" << i + 1 << ": ";
cin >> x;
soma += x^2;
}
xq = sqrt(soma/n);
cout << "\nO valor de Xq e: " << xq << endl;
return 0;
}

soma += x^2;
Do you know the meaning of ^ in C++ ? It's a bitwise operator.
I guess you want to do soma += x * x;
