With the development of IC card from a simple synchronous card to an asynchronous card, from a simple EPROM card to the internal microprocessor-based smart card (also known as CPU card), the requirements of the IC card is more and more high. The management of the card itself is more and more complex, so there is an urgent need to have a tool to solve this contradiction, and the emergence of the internal microprocessor-enabled

"As long as you stand in the air, pig can fly ." I believe many people have heard of this sentence. In the original words of Lei Jun, the so-called life means doing the right thing at the right time.

1. The role of intelligent pointers
The use of heap memory in C + + programming is a very frequent operation, and the application and release of heap memory are managed by the programmer. Programmers manage heap memory themselves can improve the efficiency of the program, but the overall management of heap memory is troublesome, C++11 introduced the concept of intelligent pointers to facilitate the management of heap memory. Use of common pointers, easy to cause heap memory leaks (forget to rel
