Use pico to type and save the following program as labrep.c. Compile and run the program to observe that fork() returns the value of the childs PID to the parent process and zero to the child process. (You dont have to type the comments.)

#include 

#include 

main ( ) 

{

 int result ;

 printf("%d: I am the parent. Remember my number! ", getpid( ) ); 

 printf("%d: I am now going to fork ... ", getpid( ) ); 

 result = fork ( ) ; 

 if (result != 0) 

 { /* the parent will execute this code */ 

 printf("%d: My child's pid is %d ", getpid ( ), result ); 

 } 

 else /* result == 0 */

 { /* the child will execute this code */ 

 printf("%d: Hi ! I am the child. ", getpid ( ) ) ; 

 exit (1) ; 

 } 

 printf("%d: like father like son. ", getpid ( ) );

}

Write the output of the program. Draw a process three and label the processes with their process IDs.
