Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.
Explanation:
Some examples are:
call by value
#include <stdio.h>
void swap(int, int);
int main()
{ int a = 10, b= 20;
swap(a, b);
printf("a: %d, b: %d\n", a, b);
}
void swap(int c, int d)
{
int t;
t = c; c = d; d = t;
}
OUTPUT
a: 10, b: 20
The value of a and b remain unchanged as the values are local
//call by reference
#include <stdio.h>
void swap(int*, int*);
int main()
{
int a = 10, b = 20;
swap(&a, &b); //passing the address
printf("a: %d, b: %d\n", a, b);
}
void swap(int *c, int *d)
{
int t;
t = *c; *c = *d; *d = t;
}
OUTPUT
a: 20, b: 10
due to dereferencing by the pointer the value can be changed which is call by reference
Answer:
c

<span> Directions that tells an operating system's dispatcher what to do when a process's time slice is over.Wait for the interrupt handler to be execute. Allow the scheduler to update the process table. Select the process form the process table that has the highest priority, restart the time, and allow the selected process to begin its time slice. Directions that tells an operating system's dispatcher what to do when a process's time slice is over. Signal an interrupt, save the current position, execute the current position, execute the interrupt handler, and switch to the next process until the process or processes is complete. If a process executes an I/O request, the time slice of that process will be terminated because it would waste the remaining time waiting for the controller to perform the request. A situation in a time-sharing system in which a process does not consume the entire time slice allotted to it.

Answer:
int main()
{
int number;
printf("Enter a number: ");
scanf_s("%d", &number, sizeof(number));
for (int i = 1; i <= 2; i++) {
printf("%d*%d=%d\n", number, i, number * i);
}
}
Explanation:
I used the safe scanf_s() that takes a third parameter to indicate the size of the buffer. In this case it is the size of an integer.
