Reviewing IPC 144

The Question Mark Operator

c = a > b ? 100 : 200;

It replaces an if statement and is much faster. If a is greater than b then 100, else 200.

Please note: The types 100 and 200 must be the same type or else it will not work.

Function Calls

printf("%d  %d, b, b = b + 1);

It returns 21 21. Why? Some compilers stack the arguments and read the last argument first. Therefore, it would see b as 21 as well.
