条件/三元运算符如何工作?C ++ [英] How does the conditional/ternary operator work? C++

问题描述

以下代码的文字翻译是什么?另外，请解释它的含义以及使用此运算符的不同方式.

What would be the literal translation for the following code. Also, please explain what it meaning and the different ways of using this operator.

int i = 1, j = 2; 
 cout << ( i > j ? i : j ) << " is greater." << endl; 

有关三元运算符的任何其他有用或附加信息，将帮助我更好地理解它.

Any other useful or additional information about the ternary operator that will help me understand it better would be much appreciated.

推荐答案

( i > j ? i : j )

基本上是指:

如果(i> j)为真，则返回 i ，否则返回 j

if (i > j) is true return i, else return j

附带说明:这与MS Excel的if-formula非常相似

Side note: This is very similar to MS Excel's if-formula
