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。 　　　　　　

-Determine 101-200 between the number of primes, and output of all primes. Program analysis: judgment Primes: respectively removed by a number of 2 to sqrt (number), divisible, it indicates that this number is not a prime number, on the contrary is a prime number.
