Conditional Operators

The graphical representation of

(condition ? trueValue : falseValue)

is as follows:

The multiplex operator can also be used directly with several arguments (left image), the right image shows the identical functionality built as a cascade of several Mux operators:

The above example is equivalent to

(condition1 ? (true1Value : condition2 ? ( false1true2Value : false1false2Value))),

i.e., the first argument has priority over the others. A cascaded Mux operator with n logical condition arguments can select between n+1 arguments between which it switches. The type of the arguments is arbitrary, but all arguments must be of a compatible type.

The above example is equivalent to

switch (self->switch_value->val)
{
case 1 :
 {
   out_case = case_1;
   break;
 }
case 2 :
 {
   out_case = case_2;
   break;
 }
default:
 {
   out_case = case_default;
   break;
 }
}
