计算质数的优秀算法,时间快，耗费资源少等优点-Excellent algorithm for calculating prime numbers, time, speed, cost and fewer resources

资料里的是Java的程序代码，有求n个奇数的和，输出给定范围的质数，阶乘的计算，输出前五个被3整除的数，用非递归的方法打印Fibonacci数列。-Data is the Java code, n odd and output demand given the scope of the prime numbers, the factorial calculation output five divisible by 3, non-recursive print the Fibonacci seq

质数计算器：判断一个数字是否为质数。C#编写，使用新进程进行计算，可在计算中直接退出；带有错误捕捉。我的第一个C#程序-standard calculator : Judging whether a digital standard. C# development, the use of the new process, which can be calculated directly With the wrong capture. My first one C# procedures
