Please i need help in this question in c programming language

Assume an environment in which transactions and responses are being sent across a network. When a transaction is sent, a timestamp is created and attached to the transaction. When the response is received the time is noted. Using an integral timestamp, as shown in program9-8, write a function to determine the elapsed time in hours, minutes, and seconds between the transaction submitted and its response. Assumeno transaction takes longer than 24 hours. Create a test driverto validate your function. Test the function with at least five test cases, including one that spans midnight. For example: Enter Time 1 HH:MM: SS 04:10:15 Enter Time 2: HH:M: SS 06:12:20 Time Stamp 1: 04:10:15 Elapsed Time: 02:02:05
