The allocation of the memory is done in a linear search through the array to find an unoccupied place. If the memory pool is very small, this might even be reasonable. However not recommended for larger memory pools. 这里内存池对外分配内存的时候是通过对一个数组进行线性查找从而找到未被占用的...

A data member of the Queue class should point to the first Node of a queue. For convenience, you could also have data members for the last node and the number of nodes in the queue(for quickly adding nodes and detecting full and empty and limit of nodes amount). Also a data member s...
