输入一个数，可以判断这个数是否为质数，如果是质数，则把它输出，每隔10个数换一行。-Enter a number, can determine whether the number of prime number, if it is prime number, while its output for every 10 the number of his party.

运用函数，能够将100以内的质数求出，改动运行次数，能够求出随意的质数-Use function obtained the primes less than 100, changes the number of runs can be obtained at random primes

用C代码实现求质数的简单方法，枚举法。适合初学者使用学习。-The simplest way to use C code required primes, enumeration method. Suitable for beginners to learn.
