(((c++ ))) Grade Point Average Write a program that reads the number of courses N taken by a student. The program reads the grade and the credit hours for N courses. The program calculates and prints the student grade-point average GPA. The grades are represented by 4 as the weight of A, by 3 as the weight of B, by 2 as the weight of C, by 1 as the weight of D, and by 0 as the weight of F.

GPA = sum(credit * weight) / sum(credit)

The GPA of the below input / output sample is:

GPA = (3 * 3 + 3 * 4 + 4 * 2 + 2 *1) / (3 + 3 + 4 + 2) = 2.58333

Sample inputs / outputs:

Enter the number of courses: 4

Enter the grade and credit of course number 1: B 3

Enter the grade and credit of course number 2: A 3

Enter the grade and credit of course number 3: C 4

Enter the grade and credit of course number 4: D 2

The student GPA is 2.58333
