Grade Evaluator in C++

Here is another example of my work in C++ to compute and evaluate the grades of the student whether the student, pass or failed in the subject. The code using two dimensional array as its data structure and looping statements. I hope you will find my work useful in learning C++ programming.

 Program Listing

#include <iostream>

 using namespace std;

 main()
 {
     string grading[3] = {"Prelim","Midterm","Endterm"};
      int grade[3][1];
     int add=0, solve=0;
     bool remarks;
     cout << "Simple Grade Solver 1.0";
     cout << "\n\n";
     for (int a=0; a<3; a++) {
       for (int b=0; b<1; b++)
