C 练习实例33 - 质数(素数)判断 C 语言经典100例 题目:判断一个数字是否为质数。 程序分析:质数(prime number)又称素数,有无限个。一个大于1的自然数,除了1和它本身外,不能被其他自然数整除。 程序源代码: 实例 [mycode3 type='cpp'] #include #include #de
Python和C运算速度对比实测 久闻python的底层代码是C写的,运行起来也要比C慢很多。但是一直没有见过量化的对比数据,今天正好有空亲自写了点代码小测了一下,在这里把结果分享一下。 OS:Ubuntu 16.04 Python IDE:Pycharm C IDE:GCC+Sublime Text3 Code: Prime Number Selection 首先是C的程序。 程序很简单,主要...
