Branching - Tweet decoder In this assignment, you'll decode Twitter messages that include Internet abbreviations, such as LOL and IRL. The starter program decodes two abbreviations 1. Expand the number of abbreviations that can be decoded to include the following AFK = away from keyboard NVM never mind BFF best friends forever FTW for the win IIRC = if I recall correctly TTYL talk to you later IMHO = in my humble opinion Save your solution for this step in a file named "step1.cpp". You'll need to submit each step as a separate file 2. Allow the user to enter a complete tweet (160 characters or less) as a single line of text. Use getline to get the single line of text then resize (or truncate) to 160 characters Search the resulting string (using string's find function) for those common abbreviations and print a list of each abbreviation along with its decoded meaning Save your solution for this step in a file named "step2.cpp". You'll need to submit each step as a separate file 3. Convert the user's tweet to a decoded tweet, replacing the abbreviations directly within the tweet. You only need to replace the first instance of a particular abbreviation Save your solution for this step in a file named "step3.cpp". You'll need to submit each step as a separate file Here is an example program execution for step 3 (user input is highlighted here for clarity) Enter tweet: I'm going to hang out with my BFF IRL tomorrow
