指针对C语言的重要性不言而喻，它是C的灵魂，我将指针和数组比作习武之人的任督二脉，如果学习C语言之人一旦将其二脉打通，那么对C语言的理解和使用就犹如内功层次的提升，跟表面的花架子将不再同一档次。(The pointer on the importance of the C language it is self-evident, it is the soul of C, I will be two big puleses compared to the pointer and array martial arts, if learning C language once the portal opened, so understanding and use of the C language is like the internal level, with the surface of the flower shelf will no longer be the same a grade.)
