Write a simple C or C++ program to call fork() and print a message with its PID (e. g., "This is process PID") where PID is the process ID of the proce

This is written in C++

This program uses no comment; See explanation section for detailed explanation

#include <iostream>

using namespace std;

void fork (string PID)

{

 cout<<"This is process "<<PID;

}

int main ()

{

 string PID;

 cout<<"Enter Process ID: ";

 cin>>PID;

 fork(PID);

}

Explanation:

This line includes the header file

#include <iostream>

This line calla namespace std

using namespace std;

This line defines function fork()

void fork (string PID)

{

This line executes the necessary operation

 cout<<"This is process "<<PID;

}

The main method starts here

int main ()

{

This line declares string PID as the process ID

 string PID;

This line prompts the user for process ID

 cout<<"Enter Process ID: ";

This line inputs PID from the user

 cin>>PID;

This line calls the function fork()

 fork(PID);

}

yes, but you must first make sure that you'll be able to make your turn or you can crash into other vehicles.
