 // Read the code and then answer the questions below
 
 // a) How many function calls are there in this file? Write down all the lines where a function call is made
+// -) functions called are:

 // b) Run the code and identify the line where the error is coming from - why is this error occurring? How can you fix this problem?
+// The error is coming from line: 5.
+// This error is occurring because a , is missing inside the replaceAll() so the two inputs aren't separated.
+// I will fix this error by adding , after the first input inside replaceAll()
+// replaceAll("," "")   Changed to >>
+// replaceAll(",", "")
 
 // c) Identify all the lines that are variable reassignment statements
