Once you get more than one person writing it, it's very easy for any two programmers to overwrite each other's work if they're working on the same file, or to send incompatible instructions that simply causes the computer to choke, and this problem grows larger the more programmers are involved.
当撰写程序的人超过一个的时候 如果他们用相同文件进行操作，要写出2个程序或者 互相充实各自的程序会变得很容易 否则传输一个没有完成的程序 很容让电脑当机 问题会变得很严重 会有更多的程序被牵连其中
