21. CODE: Read the Board from a File

Reading the Board from a File

Until now, the board has been declared and initialized in the main() function. As discussed in the previous notebook, you will need a function to read the board in from another file in order to make the program a little more flexible and user-friendly.

The first step in this process will be to write a ReadBoardFile function that reads in the file and prints each line to cout . The output should look like the 1.board file, which can be opened in the editor below:


To Complete This Exercise:

  1. Write a function void ReadBoardFile which reads lines from a file. Write each line to cout , followed by a newline character "\n" . The function should accept a string argument, which represents the path to the file. For now, since ReadBoardFile does not need to return anything, you can use a void return type.
  2. Call ReadBoardFile from main using the argument "1.board" .

Note: you will need to include the fstream class, and you may want to have using std::ifstream to use the ifstream object without having to write std:: in the rest of your code.
