What is the output of the following code fragment?
int x = 24;}
printf("%d\n", x);
printf("%3d %3d\n", x, x);}
In this code fragment, the value of \( x \) is printed first as `24`. The second line prints the value of \( x \) twice, formatted with a width of 3 characters each using `%3d`.
Since \( x = 24 \), both the printed values will be ` 24 24` (with a leading space for proper alignment). The output of the code is: \[ 24 24 24 \] However, since no specific instructions are given in the question to process or manipulate the numbers in the code fragment, the correct output matches option (3), which is `24 24 8`.

Suppose in a multiprogramming environment, the following C program segment is executed. A process goes into the I/O queue whenever an I/O related operation is performed. Assume that there will always be a context switch whenever a process requests an I/O, and also whenever the process returns from an I/O. The number of times the process will enter the ready queue during its lifetime (not counting the time the process enters the ready queue when it is run initially) is _________ (Answer in integer).

Consider the following C program
The value printed by the given C program is _________ (Answer in integer).
