?: (conditional)

int s = 0;
for(int i = 5; i < 100; i += 5) {
  s = (i < 50) ? 0 : 255;
  line(30, i, 80, i);
Description A shortcut for writing an if and else structure. If the condition evaluates to true, expression1 is evaluated and returned. If the condition evaluates to false, expression2 is evaluated and returned.

The following conditional:
result = condition ? expression1 : expression2

is equivalent to this structure:
if (condition) {
result = expression1
} else {
result = expression2
condition ? expression1 : expression2
condition any valid expression which evaluates to true or false
expression1 any valid expression
expression2 any valid expression
Returns Variable, dependent on the datatype of the expressions
