* [Description]
*
* Larry graduated this year and finally has a job. He's making a lot of money, but
* somehow never seems to have enough. Larry has decided that he needs to grab hold
* of his financial portfolio and solve his financing problems. The first step is to
* figure out what's been going on with his money. Larry has his bank account
* statements and wants to see how much money he has. Help Larry by writing a
* program to take his closing balance from each of the past twelve months and
* calculate his average account balance.
*
* [Input]
*
* The input will be twelve lines. Each line will contain the closing balance of his
* bank account for a particular month. Each number will be positive and displayed
* to the penny. No dollar sign will be included.
*
* [Output]
*
* The output will be a single number, the average (mean) of the closing balances
* for the twelve months. It will be rounded to the nearest penny, preceded
* immediately by a dollar sign, and followed by the end-of-line. There will be no
* other spaces or characters in the output.

*
* By: Kevin Colour
*
* There are three ways I could to do a swap.
*
* 1. Bitwise swap
* 2. Addition swap
* 2. Temporary Holder
*
* However there are mixed reviews as to which method is
* better, preforms better. Bitwise and Addition swap may
* be faster in some cpu architectures due to the way
* low level operations had been implemented.
*
* Typically bitwise operations are faster than addition
* but most modern architectures have implentations that
* allow these operations to be done on a single CPU cycle.
*
* This however is not the end of the story. Due to the nature
* of preprocessors and complier optimizations using a temporary
* variable may be sufficiently efficient. Modern compliers will
* preform some sort of trickery, xchg instruction, which in some
* architectures such as x86 may prove faster.
*
* Authors note: In terms of readability, all of them make sense.
* When adding two things together in a computer you are virtually
* making a copy, i.e what is being added isn't destroyed. Upon seeing
* this the first swap using addition is easy to understand and then other.
* With a bitwise swap you are 'adding' the bytes, I see it as layering the
* bytes on top of one another i.e. using XOR (int) operation is like
* applying a 90 degree polarized filter.
*
* A warning though! Using addition or bitwise method may fail and cause
* a lot of frustration if the same pointer is used; and so these methods
* require an additional step: checking to see if it is the same data.

/**
* 无名管道，它只能用于具有亲缘关系的进程之间，这就大大地限制了管道的使用。有名管道的出现突破了这种限制， 它可以使互不相关的两个进程实现彼此通信。
* 该管道可以通过路径名来指出，并且在文件系统中是可见的。在建立了管道之后，两个进程就可以把它当作普通文件一样进行读写操作，使用非常方便。
* 不过 FIFO 是严格地遵循先进先出规则的，对管道及 FIFO 的读总是从开始处返回数据，对它们的写则把数据添加到末尾，它们不支持如 lseek()等文件定位操作。
* 有名管道的创建可以使用函数 mkfifo()，该函数类似文件中的 open()操作，可以指定管道的路径和打开的模式
*
* 在创建管道成功之后，就可以使用 open()、 read()和 write()这些函数了。与普通文件的开发设置一样，对于为读而打开的管道可在 open()中设置 O_RDONLY，
* 对于为写而打开的管道可在 open()中设置 O_WRONLY，在这里与普通文件不同的是阻塞问题。由于普通文件的读写时不会出现阻塞问题，而在管道的读写中却有阻塞的可能，
* 这里的非阻塞标志可以在 open()函数中设定为 O_NONBLOCK。下面分别对阻塞打开和非阻塞打开的读写进行讨论。
* （1）对于读进程。
* 若该管道是阻塞打开，且当前 FIFO 内没有数据，则对读进程而言将一直阻塞到有数据写入。
* 若该管道是非阻塞打开，则不论 FIFO 内是否有数据，读进程都会立即执行读操作。即如果 FIFO内没有数据，则读函数将立刻返回 0。
* （2）对于写进程。
* 若该管道是阻塞打开，则写操作将一直阻塞到数据可以被写入。
* 若该管道是非阻塞打开而不能写入全部数据，则读操作进行部分写入或者调用失败
*
* 函数原型 int mkfifo(const char *filename,mode_t mode)
* 函数传入值 filename：要创建的管道名字(包含路径)
* 函数传入值 mode：
* O_RDONLY：读管道
* O_WRONLY：写管道
* O_RDWR：读写管道
* O_NONBLOCK：非阻塞
* O_CREAT：如果该文件不存在，那么就创建一个新的文件，并用第三个参数为其设置权限
* O_EXCL：如果使用 O_CREAT 时文件存在，那么可返回错误消息。这一参数可测试文件是否存在
* 函数返回值：
* 0：成功
* EACCESS：参数 filename 所指定的目录路径无可执行的权限
* EEXIST：参数 filename 所指定的文件已存在
* ENAMETOOLONG：参数 filename 的路径名称太长
* ENOENT：参数 filename 包含的目录不存在
* ENOSPC：文件系统的剩余空间不足
* ENOTDIR：参数 filename 路径中的目录存在但却非真正的目录
* EROFS：参数 filename 指定的文件存在于只读文件系统内
