    cin >> midterm;
    while (midterm < 0 || midterm > 200)
    {
        cout << "Please enter valid amount must be 0 or greater or 200 or less. please enter grade: ";
        cin >> midterm;
    }

    }
    else if (total > 280 && total <= 320)
    {
        cout << "your letter grade is C";
    }
    else if (total > 240 && total <= 280)
    {
        cout << "your letter grade is D";
    }
    else if (total <= 240)
    {
        cout << "your letter is F";
    }
}

CodePudding user response：

Put your whole code in a loop that never stops.

Example:

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
    while(true) {
        int midterm=0;
        int final=0;
    
        cout << "please enter midterm grade: ";
        cin >> midterm;
        while (midterm < 0 || midterm > 200)
        {
            cout << "Please enter valid amount must be 0 or greater or 200 or less. please enter grade: ";
            cin >> midterm;
        }
        cout << "please enter final grade: ";
        cin >> final;
        while (final < 0 || final > 200)
        {
            cout << "Please enter valid amount must be 0 or greater or 200 or less. Please enter grade";
            cin >> final;
        }
    
        int total;
        total = final   midterm;
    
        if (total > 360 && total <= 400)
        {
            cout << "your letter grade is A";
        }
        else if (total > 320 && total <= 360)
        {
            cout << "your letter grade is B";
        }
        else if (total > 280 && total <= 320)
        {
            cout << "your letter grade is C";
        }
        else if (total > 240 && total <= 280)
        {
            cout << "your letter grade is D";
        }
        else if (total <= 240)
        {
            cout << "your letter is F";
        }
        cout << "\n";
    }
}
