Answer:
Time plot.
Explanation:
A time plot, also known as a time series can be defined as a graphical representation of a pre-defined value (data) against time.
If we recorded the average U.S. Housing Price every month for the next year, the graphical display which is most appropriate to display the data is a time plot.
Generally, when representing data that changes with respect to time or that are random in nature; a time plot is considered to be the most effective graphical display to use.
In this scenario, the average U.S. Housing Price that is observed should be plotted against the time of occurrence (months) over a year.
Answer:
This is the complete correct program:
#include <stdio.h>
#include<sys/types.h>
#include<unistd.h>
int value = 128;
int main()
{
pid_t pid;
pid=fork();
if (pid==0) /* child process */
{
value +=8;
return 0; }
else if (pid > 0) {/* parent process */
wait (NULL);
printf ("PARENT: value =%d\n" ,value); /* LINEA */
return 0;
}
}
The output of the LINE A is:
PARENT: value = 128
Explanation:
The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.
In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement
value +=8;
Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :
else if (pid > 0)
{ wait (NULL);
printf ("PARENT: value =%d\n" ,value);
return 0; }
So the value 128 is printed at the end in the output.
wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.
So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.
Answer:
There were three important features to Baroque music: a focus on upper and lower tones; a focus on layered melodies; an increase in orchestra size. Johann Sebastian Bach was better known in his day as an organist. George Frideric Handel wrote Messiah as a counterargument against the Catholic Church
Answer:
True.
Explanation:
Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers have several CPUs, have very fast processor speeds, can supporting multiple operating systems and have huge amounts of storage capacity. As a result, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.
You must be careful while handling a hard drive because If you’re not careful with it the hard drive may corrupt or crash.
