Answer:
String date = "21/05/2020";
String dayStr = date.substring(0,2);
int day = Integer.parseInt(dayStr);
System.out.println(day);
Explanation:
Create a variable called <em>date</em> which holds the current date
Create a variable called <em>dayStr</em>. Initialize it to the day part of the <em>date</em> using the substring method
Create a variable called <em>day</em>. Parse the <em>dayStr</em> and assign it to the <em>day</em>
Print the <em>day</em>
Answer:
It balances a tree when a long path exist in the left subtree of the left of the root.
Explanation:
Rotation is an operation which is performed on the binary tree which changes the structure of the binary tree but it does not interfere with the order of elements.
A single right rotation strategy is basically for re balancing the tree.When there is along path which exists in the left subtree of the left of the root.
I believe it is That product is sustainable.
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.
