Previously parent process was terminating before the child process ...as a result there is no one to execute the termination section of the child process and the child is now an orphan child
so to overcome this i have used a system call wait in which the parent process is paused and the child process is initially finished and after that parent process is terminated .
So that the shell will not be hanged.

Now i have taken 3 cases using switch statement 
First case is when f_ret is a negative value,it will print an error
Second case is when f_ret is zero , then it is a child process.
Else it is a parent process.

Here i have declared a variable f_ret whose datatype is pid_t
After that i have created a child process using fork() 
Here fork is returning two values which will be copy on right in the f_ret
One value is for parent process and that value will be the PID of the child process.
Another value will be 0 when fork() is executed by the child process
