24. CODE: Parse Lines from the File

Parse Lines from the File

Now that you are able to read a board line by line from a file, you will want to parse these lines and store them in a vector<int> . In this exercise, you will focus on a helper function to do this string parsing.

We have included a test in the main to ensure that the function is working correctly. If everything works, you should see:

TestParseLine: passed

To Complete This Exercise:

Write a vector<int> ParseLine function which accepts a string as an argument. Use std::istringstream to parse the line by comma char s, and store the int s in a vector<int> . ParseLine should return the vector after parsing.

Note: you will need to #include <sstream> to use istringstream . Additionally, you may want to add using std::istringstream; to your program. Finally, remember that each line of the board will look something like: 1,0,0,0,0, , so you may want to stream an int and a char with each pass through a while loop.
