In shortestPath I've tried to call a Get method I wrote in the matrix.cc file, but I can't figure out how to call the function on the object of that class. This is the line of code I have: char exp = mat.Get(0, 0); I'm more concerned now with how to call the function on the object. the object of the matrix class is called mat. The parameters specify which character to return.
