Plz i need help with this C++ program

Student Generated Code Assignments Option 1: Write a program that will read in 3 grades from the keyboard and will print the average (to 2 decimal places) of those grades to the screen. It should include good prompts and labeled output. Use the examples from the earlier labs to help you. You will want to begin with a design. The Lesson Set I Pm-lab Reading Assignment gave an introduction for a design similar to this problem. Notice in the sample run that the answer is stored in fixed point notation with two decimal points of precision. Sample run: Please input the first grade Please Input the second grade 98.3 Please Input the third grade The average of the three grades is 96.77

Explanation / Answer

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
   double grade1, grade2, grade3, avg;

   cout << "Please enter first grade" << endl;
   cin >> grade1;
   cout << "Please enter second grade" << endl;
   cin >> grade2;
   cout << "Please enter third grade" << endl;
   cin >> grade3;

   avg = (grade1 + grade2 + grade3) / 3;
    cout << "The average of three grades is " << int(avg * 100) / 100.0;

    return 0;
}
