计算机技术的第一次出现在美国的1…
One of the first occurrences of computer technology occurred in the USA in the 1880s. It
was due to the American Constitution demanding that a survey is undertaken every 10 years.
As the population in the USA increased, it took an increasing amount of time to produce the
statistics. By the 1880s, it looked likely that the 1880 survey would not be complete until
1890. To overcome this, Herman Hollerith (who worked for the Government) devised a machine
which accepted punch cards with information on them. These cards allowed a current
to pass through a hole when there was a hole present.

C++中,成员指针是最为复杂的语法结构。但在事件驱动和多线程应用中被广泛用于调用回叫函数。在多线程应用中,每个线程都通过指向成员函数的指针来调用该函数。在这样的应用中,如果不用成员指针,编程是非常困难的。 -a member of indicators is the most complex grammatical structure. However, in event-driven multi-threaded applications and are widely used in the callback function to call. In multi-threaded applications, each thread through the indicators point to a member function to call the function. In such applications, if it is not a member of indicators, programming is very difficult.
