Ти ако мислиш че БГ програмистите са по долу от другите много се лъжеш пич, да не си 5-ти клас?
За това ли SAP имат лаборатория тук, че и търсят още персонал, но това е предполагам защото БГ програмистите са заядливи "копелета" които знаят всичко и го израждат в swap файлове, CString-ове и бира.
Айде сега поздрав за всички C++ програмисти и т.н.:
