Description

Assignment – 4

The aim of this assignment is to make you familiar with UDP Socket Programs (server & client) and understand the skeleton code. Use the given codes in the following programming assignments:

1. Ping-Pong

You have to write a client ping program in C. Your client will send a simple “ping” message to a server, receive a corresponding “pong” message back from the server, and determine the delay between when the client sent the ping message and received the pong message, which is termed as the Round-Trip Time (RTT).

For the assignment, your ping program has to send 10 ping messages to the target server over UDP. For each message, the client is to determine and print the RTT when the corresponding pong message is returned.

2. Mathe-magic

You have to write a math server program in C to solve simple arithmetic problems given by a client. The server shall use a standard format for accepting inputs – operator: firstvalue: second-value. It is the server’s responsibility to understand the input and delegate to the proper methods such as “add”, “sub”, “mul”, or “div.” The result of the arithmetic operation has to be returned as a response to the client.
