Coding Tip: Use The Ternary Conditional Operator

The ternary conditional operator (?:) can be used as a short-hand version of an if statement. It is a feature of many languages.

For example, this code:

int height;
if(isTall)
    height = 50;
else
    height = 10;

can be better written as:

int height = isTall ? 50 : 10;

The ?: operator is good for replacing very simple if statements, but is bad for complicated if statements as it can harm readability.
