Question
Chapter 8.4, Problem 8.2PP
A.
Program Plan Intro
Given code:
//Include the necessary header files
#include <stdio.h>
#include "csapp.h"
//Define a main()
int main()
{
//Initialize the variable x as 1
int x=1;
//Check the condition
if(fork()==0)
//Print the statement
printf("p1: x=%d\n", ++x);
//Print the statement
printf("p2: x=%d\n", --x);
//Exit
exit(0);
}
Explanation:
The given code is used to print the output of the child and parent processes.
In the given code, the main
- The “if” condition check, function “fork()” is equal to zero.
- Condition is true, print the value of “x” by incrementing “1”. So, the value of “x” becomes “2”.
- Otherwise, print the value of “x” by decrementing “1”. So, the value of “x” becomes “1”.
- Exit from the program.
B.
Explanation of Solution
Output of the parent process:
P2: x = 0
Explanation:
In the given code, the main program initializes the variable “x” as “1”.
- The parent process check the condition, if the function “fork()” is equal to zero...
