Correct Answer: 2
Correct Answer: 10
Explanation:
Void pointer can hold address of any data type without type casting. Any pointer can hold void pointer without type casting.
Correct Answer: -2 3 0 1
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: 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: 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: Time and Space
Explanation:
Two main measures for the efficiency of an algorithm are Time and Space.
