Write the code for a client that sends the server an integer and a private FIFO name through a common FIFO. Invoke this client 3 separate times. Write the code for a server that adds the integers that it receives from all three clients and sends the sum back to all 3 clients through their private FIFOs.

This is my server and client code. I cannot seem to get the proper counts printing on the server, it spits out 0 for all clients. How can I get the proper counts to print on the server coming from the clients?

int i; // because C needs this defined as int

int x = 0;

printf(" How many clients will be accessing the server: ");

scanf("%d", &clients);

if((fda=open("commonFIFO", O_RDONLY))<0) //open commonFIFO

printf("cant open fifo to write");

read(fda, &input, sizeof(input)); //read struct

fdb = open(input.privateFIFO, O_WRONLY); //open privateFIFO

write(fdb, &input, sizeof(input));
