This is similar to how arrays are treated, where a bare array decays to a pointer, but you may also prefix the array with & to request its address. Function Pointers in the Wild Let's go back to the sorting example where I suggested using a function pointer to write a generic ...
state machine implementation in C With the help of array and function pointers, we can implement a state machine in C. The function pointer store the address of the function which will be invoked at defined state and events. A finite state machine is one of the popular design patterns, it...

连起来就是:fp1 is a pointer to a function that takes an int and returns a pointer to an array of 10 void pointers. 是不是超简单?这个方法我其实是从Thinking in C++, Volume 1学到的,然后自己总结了下,并取了个沙雕但是个人认为有助于理解的名字,不懂为什么其他教程都没有这样教,再来一个: ...
