#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>

int main(int argc, char** argv)
{
pid_t child_pid;
 char *message;
  char s[500];
   char* cwd;
    char buff[500];
     char *directory  ;
      int ret;

int repetition;
printf("So far only one process is runing\n");
child_pid = fork();
switch (child_pid)
{
case -1:
printf("fork process failed\n");
exit(1);

case 0:
message = "J am a child";
 printf( "My working directory is %s.\n", getcwd(buff, 500));
 printf("New directory: \n");
         scanf("%s",s);
         chdir(s);

break;
default:
message = "J am a parent";

break;
}
printf( "My working directory is %s.\n", getcwd(s, 500));
