Why using if in this way is preventing it from running

so here the if inside the loop is it possible to write the if statement in an optimized way or should I just split the two conditions?

#include <iostream>
using namespace std;

int main()
{
    int grade, counter = 1, total = 0, average;

    while (counter <= 10)
    {
        cout << "Enter grade /100: ";
        cin >> grade;

        if (grade < 0 && grade > 100) //HERE PLEASE
        {
            cout << "invalid grade value." << endl;
            cout << "Reenter grade value */100*: ";
            cin >> grade;
        }
        
        total = total + grade;

        counter++;
    }
    
    average = total / 10;
    
    cout << "\nThe class average is:  " << average << endl;

    return 0;
}
