Sometimes segmentation fault or sometimes unwanted output occurs at the receiver side  . When i use character array instead of pointer all works well .

Why is this happening????

Implement the client server application using pipes by inter-process communication

server has to generate clients and clients will communicate with server through pipes . Clients  will send their parameters and server will accept it and depending upon the request the server will transfer the request to other process through pipes which perform the corresponding operation and send the result back to server and server will send the result back to corresponding requester.

First implement it with on client and then move forward with multiple clients.

All E-10 batch members will post their status and queries regarding project on this thread only .
