Babylonian Algorithm with C++ unable to get loop to run -


is refusal program produce result consequence of unable loop?

please find below code more information.

#include <iostream> #include <cmath> #include <iomanip>  using namespace std;  int main() {     double x, squareroot, oldsquareroot, counter=0;     cout << "enter positive number: " ;     cin >> x ;     {         (oldsquareroot = x/2; abs(squareroot-oldsquareroot) >= 1e-9 &&   abs(squareroot - oldsquareroot)>=(1e-8*x);counter++ )         {              squareroot = (squareroot+x/squareroot)/2;         }      }     cout << setprecision(15);     cout << "the value of squareroot is:" << squareroot << endl;     cout << "the number of interations required computation is:" <<  counter << endl;     return 0;   }

there mistakes. works fine.

#include <iostream> #include <cmath> #include <iomanip>  using namespace std;  int main() {     double x, squareroot, oldsquareroot, counter = 0;     cout << "enter positive number: ";     cin >> x;     {         squareroot = x; // fixed error 1: using of uninitialized variable.         (oldsquareroot = x / 2; abs(squareroot - oldsquareroot) >=  1e-9 && abs(squareroot - oldsquareroot) >= (1e-8*x); counter++)         {             oldsquareroot = squareroot;// fixed eror 2: oldsquareroot not changed in loop , can't exit.             squareroot = (squareroot + x / squareroot) / 2;         }     }     cout << setprecision(15);     cout << "the value of squareroot is:" << squareroot << endl;     cout << "the number of interations required computation is:" << counter << endl;     return 0; }

i hope you.

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
