用三元运算符求最大数的程序-yiteyi-C++库

任务是编写一个程序，使用三元运算符在…之间：

null

两个数字
三个数字
四个数字

例子 :

Input : 10, 20 Output : Largest number between two numbers (10, 20) is: 20Input : 25 75 55 15Output : Largest number among four numbers (25, 75, 55, 15) is: 75

A. 三元运算符 具有以下形式：，

exp1 ? exp2 : exp3

表情 exp1 将始终进行评估。执行 exp2 和表3 取决于调查结果 exp1 .如果 exp1 那么是非零吗 exp2 将被评估，否则，表3 将进行评估。

程序来查找其中最大的数字 两个数字 使用三元运算符 .
