Correct Answer: It is NOT appropriate to use assertions to validate command-line arguments
Explanation:
A is incorrect. It is acceptable to use assertions to test the arguments of private methods.
B is incorrect. While assertion errors can be caught, Sun discourages you from doing so.
Correct Answer: a
Correct Answer: 3
Explanation:
The Math.floor() function in JavaScript is used to round off the number passed as parameter to its nearest integer in Downward direction of rounding i.g towards the lesser value.
Hence, math.floor(3.6) = 3.
Correct Answer: Time and Space
Explanation:
Two main measures for the efficiency of an algorithm are Time and Space.
Correct Answer: AutoSys is an automated job control system for scheduling, monitoring, and reporting These jobs can reside on any AutoSys-configured machine that is attached to a network However, in real business, you need to fire jobs not just based on scheduled time, but also based on events (like an arrival of a file), and, based on the success or failure of other jobs Autosys is a total job scheduling solution that allows you to define these events, dependencies, time schedules, alerts, etc, making it a complete data center automation tool
Correct Answer: #include "dosh" main() { Char far *scr = ( char far *) 0xB8000000; Char *seg, *off; Seg = (char *) FP_SEG ( scr ); Off = ( char *) FP_OFF ( scr ); }
Correct Answer: 65486 65486
Correct Answer: An error would be reported in the statement k++ since arithmetic on void pointers is not permitted unless the void pointer is appropriately typecasted
Correct Answer: Use the typecast scr = (char far *) 0xB8000000;
Correct Answer: 1 2
