- 1. What is Autosys? Discuss
- 2. What would be the output of the following program? # define SQR(x) (x * x) main() { int a, b = 3; a = SQR ( b + 2 ); Printf ("\n %d ", a ); } Discuss
- 3. We want to round off x, a Float to an Int value. The correct way to do so would be
Options- A. Y = ( int ) ( x + 0.5 ) ;
- B. Y = int ( x + 0.5) ;
- C. Y = ( int ) x + 0.5;
- D. Y = ( int ) ( ( int ) x + 0.5 ) Discuss
- 4. What would be the output of the following program? main() { int i = -3, j =2, k =0, m ; m = ++j && ++i || ++k ; Printf ( "\n%d%d%d%d", i , j , k , m ); } Discuss
- 5. Can you suggest any other way of writing the following expression such that 30 is used only once? a <= 20 ? b = 30 : c = 30 ; Discuss

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: 11 Because, on preprocessing the expression becomes a = ( 3 + 2 * 2 + 3), as Ist preference is multiply & then addition, it evalvates as(3+ 2 * 3 +2) = (3+6+2)=11
Correct Answer: Y = ( int ) ( x + 0.5 ) ;
Explanation:
Rounding off a value means replacing it by a nearest value that is approximately equal or smaller or greater to the given number.
y = (int)(x + 0.5); here x is any float value. To roundoff, we have to typecast the value of x by using (int)
Example:
#include
int main ()
{
float x = 2.6;
int y = (int)(x + 0.5);
printf ("Result = %d\n", y );
return 0;
}
Result : 3
Correct Answer: -2 3 0 1
Correct Answer: *( ( a <= 20 ) ? &b : &c ) = 30;
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: a
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: Final
Explanation:
Once a method declared as Final cannot be overriden
Correct Answer: #include "dosh" main() { Char far *scr = ( char far *) 0xB8000000; Char *seg, *off; Seg = (char *) FP_SEG ( scr ); Off = ( char *) FP_OFF ( scr ); }
