max and min

[persades]

im writing a program that will give me the sum of any given inputs the average as well as the highest number and the smallest, this is what i have but I'm having trouble displaying the highest and smallest , i would appreciate any help thanks :)

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

int main() {
	float numb;
	float numbsum = 0;
	float numbofentries = 0;
	cout << "This program analyzes numerical input.\n\n";
	cout << "Enter a number (0 to exit): ";
	cin >> numb;
	while(numb != 0) {
		numbsum = numbsum + numb;
		numbofentries++;

		cout << "Enter a number (0 to exit): ";
		cin >> numb;}
 	double high = numb;
 	double low = numb;
 	if (numb > high) {
		high = numb;
	} else {
		if(numb < low) {
			low = numb;

}

cout << "\n\n";
cout << "Summation: " << numbsum << endl;
cout << "Average value: " << numbsum / numbofentries << endl;
cout << "Smallest value: " << low << endl;
cout << "Largest Value: " << high << endl;
    return 0;
}
}

if you declare variables inside the loop, they have a limited scope and therefore are destroyed at each iteration, otherwise if the state after the loop, just take the last value entered in numb

double high = 1 , low = 0 , numb = 1 , numb_sum = 0 ;
int numb_of_entries = 0 ;

while ( numb != 0 )
{
        cin >> numb ;

        numb_sum += numb ;

        if ( high < numb )
        {
               high = numb ;
        }
        else if ( low > numb )
        {
               low = numb ;
        }
        ++numb_of_entries;
}

cout << low << " -- " << high << " -- " << numb_sum / numb_of_entries  <<'\n' ;

its any given inputs until the user puts "0"
