Question

PostgreSQL

we have a configuration file

<?php
return [
  'db' => [
    'driver' => 'Pdo',
    'dsn' => 'mysql:dbname=dddddd; host=111.111.111.115',
    'username' => 'nnnnnnn',
    'password' => 'fffffff',
    'driver_options' => [
      PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
    ],
  ],
  'service_manager' => [
    'factories' => [
      'dbAdapter' => \Zend\Db\Adapter\AdapterServiceFactory::class,
    ],
  ],
];

Answer 1

doesn't work
any more suggestions

Answer 2

Then, that '0' == 48, and the indexing of the ndigit array (like any other) starts from zero.

Answer 3

In my mind, it's done like this:

#include <ctype.h>

if( isdigit( c ) )
  ++ndigit[c - '0'];
else if( isspace( c ) )
  ++nwhite;
