It is C++ question.

1. 13 points) Write a program to: a. Prompt the user for the number of courses: b. Prompt the user to enter the grade for each course. User should be given the choice to enter either letter grades or grade points. c. Prompt the user to enter hours for each course. d. Using the functions described below, calculate grade point average (gpa). Use the following formula for calculating spa: Gpa = ((gradePoints hours))/(Zhours) In the formula above, gradePoints refers to grade points received in a course and hours refers to hours for that course. For example, for PROG1955, the hours would equal to 5 and grade points will depend on the grade received. For this program, use the following table to find grade points corresponding to a received grade: Grade Points Grade A B C D F 3.0 2.0 1.0 For example, if you wanted to find gpa for two courses in which grades were 'A' and 'B' respectively and hours were 5 and 4 respectively, the gpa would be (4.0*5)+(3.0*4))/(5+4). Your program must use functions with the following prototypes: float Gpa(const char grades),const int hours[], int arrLength); float Gpalconst float gradePoints[], const int hours[], int arrLength); float GradePoints(char grade)
