Need some help with question. Need to solve it in C++. Please help me,need this urgently. Thanks for the answer!

4. For example, you did 4 courses last semester and received grades as follows: CSE115 ( 3 credits, A-), CSE115L ( 1 credit, A), MAT120 ( 3 credits, A-), MAT125 ( 3 credits, B+). Check NSU grading policy for calculating your CGPA. [Hint: The CGPA is calculated by multiplying the overall grade score by the credit score of each subject by the total credit scores.] Write down a program that reads credit hours and earned grade points for N courses and prints the final CGPA for that semester. You must use the concepts of dynamic memory allocation and array to implement the logic here. 4.
