The output is not correct. Something is wrong with the calculation process. Is there anything wrong with it?

Question

#include <iostream>
#include <iomanip>
using namespace std;

int main() {

float x, sum;
int i, n,p , s;
cin >>p ;
while (cin >> n) {
for (i=0; i<n; i++){
cin >> s;
sum = sum+s;
}
x= sum/n;
cout << fixed << setprecision(2) << x << endl;
}
return 0;
}

Answer 1

Write your program in code then attach your code link into the question so that we can run it. Nobody wants to copy your code to run it.
