Drill 7-8-9 (Chapter 4)

[pantera]

My program for Drill 7-8-9... Still not sure if this is expected by
the requirement of the drills, especially, the Drill 9.
// Drill 7 - Chapter 4
#include "std_lib_facilities.h"
int main()
{
const double cm_per_m = 100;
const double cm_per_inch = 2.54;
const double inch_per_foot = 12;
double x;
double smallest = 0;
double largest = 0;
string s = " ";
double sum = 0;
int counter = 0;
cout << "Enter a number, followed by its unit: ";
while(cin>>x>>s && (s=="cm"||s=="m"||s=="in"||s=="ft")) {
++counter;
if (x<smallest) {
smallest = x;
}
else if (x>largest) {
largest = x;
}
if (s=="cm")
x = x/cm_per_m; // convert to m
else if (s=="in")
x = (x*cm_per_inch)/cm_per_m; // convert to cm
to m
else if (s=="ft")
x = (x*inch_per_foot*cm_per_inch)/cm_per_m; //
convert to inch to
cm to m
sum += x;
}
cout << "Smallest: " << smallest;
cout << "\nLargest: " << largest;
cout << "\nSum: " << sum;
cout << "\nNumber of values: " << counter << endl;

I just got done with this Drill after a few hours of work. You can check it for reference. Feel free to ask any questions. Forgive the commented sections, they are from the earlier parts
