For today's lab you are going to do some string processing You are going to read a file and process the lines. A single line in the file looks like this FirstName, LastName: 1830.20, 12904.1,-123.89, 594.014 We have provided you with two sample files named sample2.txt and sample1.txt. You can use file read function to read and display the contents of file. You can also create your own file using file write function. You are going to write 4 functions that incrementally process the file 1 processFile() should loop over each line of the file calling processLine for the same and printing the result. 2.processLine() should call makeUsername and getAmount passing the first last name string to makeUsername and the string of numbers to getAmount. You need to use string operation functions to extract the relevant information from a given line of the file. Then it should return the formatted string including the results of the function calls Example: processLine ('FirstName, LastName: 1830.20, 12904.1, -123.89, 594.014) Returns Username: Flastna -Account Balance: 15295.21 NOTE- In the above example, we have passed a string to processLine function, but you should pass a line of the file instead. 3.makeUsername() should take a string with a first and last name separated by a single comma and return a new string with the capitalized first letter of the first name followed by the first 6 characters of the lastName in lower case. Example: makeUsername ('FirstName,LastName Returns Flastna HINT-You can call string split function with different delimiters. Notice, names are being seperated by"."and further each value is seperated by commas" 4.getAmount()should take a string with floating point numbers separated by commas. It should then sum each of the numbers and return the result. Example getAmount ('1830.20, 12904.1,-123.89, 594.014) Returns 15295.21
