+# About Program
+**Program:** GPA Calculator  
+**Filename:** GPAcalculator.cpp
+
+This C++ program calculates the Grade Point Average (GPA) based on the user's input of grades and corresponding credit hours for ten subjects. It uses a standard grading scale to assign grade points to letter grades and calculates the weighted GPA. The grading scale is based on Malaysia's MARA Junior Science College *(malay: Maktab Rendah Sains MARA)* grading scale for upper-form (Form 4 & Form 5).
+
+Program Components:
+- **arrSubject:** An array that stores the names of the ten subjects.
+- **arrCredHrs:** An array that stores the credit hours for each subject respectively.
+- **userGrade:** An array to store the user's input for letter grades.
+- **userPointer:** An array to store the calculated grade points based on the user's input.
+
+- **Grading Scale:** The program uses a standard grading scale to assign grade points to letter grades. The grading scale includes grades from "A+" to "F" and assigns the corresponding grade points.
+
+- **User Input:** The user is prompted to input their grades for each subject, following the grading scale. The program then calculates the corresponding grade points for each grade input.
+
+- **GPA Calculation:** The program calculates the GPA by multiplying each subject's grade points by its credit hours, summing these values, and dividing by the total credit hours (41 in this case). The result is formatted with two decimal places using setprecision from the <iomanip> library.
+
+- **Output:** The program displays the calculated GPA as the final output.
