Because it does!
"When I created object-oriented programming, C++ is not what I had in mind." -- Alan Kay
"C++ is an atrocity, the bletcherous scab of the computing world, responsible for more buffer overflows, more security breaches, more blue screens of death, more mysterious failures than any other computer language in the history of the planet Earth.
— Eric Lee Green
"Within C++, there is a much smaller and cleaner language struggling to get out." -- Bjarne Stroustrup
"Historically, languages designed for other people to use have been bad: Cobol, PL/I, Pascal, Ada, C++. The good languages have been those that were designed for their own creators: C, Perl, Smalltalk, Lisp.
— Paul Graham
"If C++ has taught me one thing, it’s this: Just because the system is consistent doesn’t mean it’s not the work of Satan." — Andrew Plotkin
"C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg". — Bjarne Stroustrup
"If you think C++ is not overly complicated, just what is a protected abstract virtual base pure virtual private destructor and when was the last time you needed one?" — Tom Cargill
"In My Egotistical Opinion, most people’s C programs should be indented six feet downward and covered with dirt." — Blair P. Houghton
