Answer 1

#include <iostream>
using namespace std;
int main()
{
    char c;
    cin >> c;
    switch (c)
    {
    case 'A':
        cout << "[90,100]";
        break;
    case 'B':
        cout << "[80,90)";
        break;
    case 'C':
        cout << "[70,80)";
        break;
    case 'D':
        cout << "[60,70)";
        break;
    case 'E':
        cout << "[0,60)";
        break;
    default:
        cout << "Error";
        break;
    }
    return 0;
