素数又叫做质数(prime number),指的是在大于1的自然数中,除了1和它本身以外不再有其他因数的自然数,否则称为合数。合数除了1和这个数本身,还能被其他正整数整除。1既不是质数也不是合数。 bool: bool类型关键字是 .NET System.Boolean 结构类型的别名,它表示一个布尔值,它的值可是true或false。

Code: Prime Number Selection 首先是C的程序。 程序很简单,主要任务就是遍历1000000以内的自然数,筛选出素数,然后结束。 为了减少printf函数对程序的延时,除了时间外其他输出全部屏蔽掉。结果如下: C用时4分54秒。 再看python的表现。 Python 和 C的算法略有不同。C是对每一个自然数进行筛查,而python先做出奇数...
