this is what the question said.
// 9-1. Reimplement the Student_info class so that it calculates the // final grade when reading the student's record, and stores that grade // in the object. Reimplement the grade function to use this // precomputed value.
this is what I thought!
1. Reimplement Student_info class 1.1 calculate the final grade WHEN reading the student's record 2. store the result in an object. 3. reimplement grade function to use this precomputed value.
But, I thought the final grade is the returned result from the grade function. but now, on "3." it's telling me to reimplement grade function to use the "precomputed value".
There is also one variable named "final" referring to the final exam grade but the data taken raw from the user's input which is not seem to fit with "calculates" as it said in the exercise!
