【解決方法】グラフィックス ライブラリ関数を使用して C++ でプログラム コードを記述し、任意の 3 つの教科の生徒の成績を棒グラフで表現します。

The program will take the input from the user for the course name and obtain marks. After taking the 6 inputs the program will draw a bar chart by labeling the bars of the bar chart according to the subject name.
The title bar of the graphic window must show your student ID.
