This code must be written in C++

Write a program to calculate grades. Follow the grading system which is attached above (For 0 = F, thats the only variable we need to worry about, the FIN,WF, and WU need to be omitted). User provides number of courses taken in a semester. Then for each course provides individual percentages. Program has to calculate the grade letter from percentage for each course. Then display the cumilative GPA of that particular semester. Write a function called letterGradeCalculator. Pass appropriate parameters to the function. Function should return the letter grade for a single course.

The grade point average is computed on a scale in which 4.00 4.00 3.70 3.30 300 2.70 2.30 - 2.00 -170 130 100 -0.70 F. FIN, WF, and WU0.00 A- B+ 8 B- C- D- D
