Q:

#define clrscr() 100

main()

{

clrscr();

printf( "%dn", clrscr() );

}

A) 100 B) 0
C) Compilation error D) Exception occurs

Answer:   A) 100



Explanation:

Preprocessor executes as a seperate pass before the execution of the compiler. So textual replacement of clrscr() to 100 occurs.The input program to compiler looks like this :

main ()

{

100;

printf("%d\n",100);

}

Note: 100; is an executable statement but with no action. So it doesn't give any problem.

Q:

What is Autosys?

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.
