Modern Periodic Table Project in C. The Modern Periodic Table project in C is a simple console application built without the use of graphics. It is developed using the C programming language for the purpose of storing name, symbol, atomic number, atomic weight, and some important properties as well as to display them as per requirement of the user. The source code for this project is complete and totally error free, and we warmly welcome any feedbacks and suggestions.

用MATLAB实现加噪信号的消噪噪,用了三种常用方法。可直接使用。 (Using MATLAB to increase noise and signal noise cancellation noise, with three commonly used methods. Can be used directly.)

  这是一个算法性能评价程序，重点在于算法性能的评价上，实现某一功能可能有很多方法，判断一个算法好坏的标准主要有时间复杂度和空间复杂度，在当今系统资源相对充足的计算机系统中,时间复杂度变成了头等问题。      对于每一个排序算法都应该有两个返回值：比较次数和移动次数，但在C语言中只能有一个函数返回值，故这里采用指针传递地址的方式通过形参的地址从而可以修改实参值，这样一来，在每个排序算法参数列表中,除了含被排序指针对象外，另外加两个整型变量指针，用于传递算法执行过程中的比较次数和移动次数。
