Using Fork() and Pipes()? Read message in w/ Pipe()? Write message to screen w/Pipe()?

I Currently have an assignment that invloves reading in a string, encrypting it, and then outputing the encrypted string.

The encryption part I have written and confident it will work.  I am now working on the Forks and Pipes and I am having a lot of trouble.  I need to create two Forks (A client, and a server).  The Client Fork reads in the string to a Pipe. Then the Server Fork reads the string from the Pipe and encrypts it.  After it is encrypted it sends the string back to the Client Fork with a new Pipe(). Then the Client Fork reads the string from the Pipe() and outputs it to the screen.

I think I have created the Forks properly:
    for (i=1; i<=2; i++) {
        if ((pid = fork()) == -1) {
            /* Fork failed! */
            perror("fork");
            exit(1);
        }

My problems revolve around the pipes.


 for (i=1; i<=2; i++) {
     if ((pid = fork()) == -1) {
        /* Fork failed! */
        perror("fork");
        exit(1);
     }
        if (pid == CHILD) {
            switch(i) {
            case 1: /* Client */
              write(p[1], buf, strlen(newbuf) + 1);
              //READS FROM NEW PIPE THE ENCRYPTED STRING
              break;

              case 2: /* Server */
              read(p[0], p[1], strlen(buf) + 1);
              //ENCRYPT
              //WRITE TO NEW PIPE, CLIENT WILL READ IT
              break;
              }
        exit(0);
       }
}

Any  help would be appreciated, I am being kind of vague... just because Im not sure what exactly to ask


Thanks
