1) 利用求n!的方法计算 2!+4!+5!的值。分别利用递归和非递归方法实现求n!。
2) 编写根据三条边求三角形面积的方法。利用该方法求以下两个三角形面积。
(1)三条边分别为:3,4,5
(2)三条边分别为:5.3, 6.2, 8
3)从命令行参数获取两个整数,找出两个整数之间的所有素数,每行输出3个数。-1) use the method seek n! 2!+4!+5! Value. Are recursive and non recursive method seeking n!. 2) seek written three sides of the triangle area under way. With this method, to calculate an area of two triangles. (1) three sides are: 3,4,5 (2) three edges, respectively: 5.3, 6.2, 83) from the command line parameters for two integers, find two integers all prime numbers between each line the number of output 3.
