Which operator can be used in some situations to simplify nested selection structures?

Answer 1

The ternary conditional operator:

x = a ? b : c;

This is the literal equivalent of the following if statement:

if (a) {

x = b;

} else {

x = c;

}

Note that a, b and c are all expressions (or compound expressions). Expression a must be a Boolean expression (evaluating true or false) while expressions b and c must be implicitly convertible to x's data type.

A real-world example:

// Return the larger of any two integers

int max (int a, int b) {

return a>b ? a : b;

}
