题目：判断101-200之间有多少个素数，并输出所有素数。

程序分析：判断素数的方法：用一个数分别去除2到sqrt(这个数)，如果能被整除， 则表明此数不是素数，反之是素数。

-Title: Determine the number between 101-200 primes and outputs all primes. Program analysis: determine the primes method: a few were removed from 2 to sqrt (this number), and if that can be divisible, it indicates that this number is not a prime number, and vice versa is a prime number.
