systematic programming

Subttle Synchronization Write a C or C++ program that takes a subtitle file(a file with .srt extension) and a signed number (in milliseconds) as its inputs and add/subtract that amount of time from all of the content of the file and return the modified file. For example, consider the following small part of a subtitle from the big bang theory: 1 00:00:03,25800:00:05,078 Ooh, it's freezing out here. 2 00:00:05,58700:00:07,877 Would you like me to... heat things up? 3 00:00:07,963 00:00:11,056 No, I want to get in the hot tub before I lose a toe. 4 00:00:12,30600:00:14,351 Oh. That is bright! 5 00:00:14,43600:00:16,915 Yeah, a new neighbor put in floodlights. 6 00:00:17,00100:00:18,251 Huh. 7 00:00:18,37300:00:19,798 So, shall we? 8 00:00:20,79000:00:24,183 No. I don't want to take my robe off under a spotlight. 9 00:00:24,37600:00:26,329 This is a candle body. The first text will appear at 00:00:03,258 till 00:00:05,078. it is very annoying if it is not synced with the movie. Your code moves all of the time forward or backward according to the number of milliseconds that the user specified
