How Does the C Ternary Operator (? :) Work?

Understanding the Conditional Operator (? :) in C -Like Languages

If you've encountered the syntax "A ? B : C" in a C -compatible language, you may wonder how to translate this into a code snippet.

To demystify this syntax, let's break it down. The conditional operator, denoted by the question mark (?), works similarly to an if-else statement. It evaluates the expression "A" as a condition. If "A" is true, the value of "B" is returned; otherwise, the value of "C" is returned.

The ternary operator is commonly employed in assignment operations, such as:

(condition) ? true-clause : false-clause

For instance, consider the following snippet:

bool Three = SOME_VALUE;
int x = Three ? 3 : 0;

This is equivalent to the following if-else block:

bool Three = SOME_VALUE;
int x;
if (Three)
    x = 3;
else
    x = 0;

In both cases, the variable "x" will be assigned the value 3 if "Three" is true, and 0 otherwise.
