C or c	Cruiser
D or d	Destroyer
F or f	Frigate
Input
The first line contains an integer T, the total number of testcases. Then T lines follow, each line contains a character.

Output
For each test case, display the Ship Class depending on ID, in a new line.

Constraints
1 ≤ T ≤ 1000
Example
Input
3
B
c
D


Output
BattleShip
Cruiser
Destroyer

answer:

#include <cctype>
#include <iostream>
#include <cstring>
#include <cstdio>
using namespace::std;
int main(int argc, const char * argv[]) {
    int t;
    cin >> t;
    while (t--) {
        char n;
        cin >> n;
        n = toupper(n);
        switch (n) {
            case 'B':
                cout << "BattleShip" << endl;
                break;
            case 'C':
                cout << "Cruiser" << endl;
                break;
            case 'D':
                cout << "Destroyer" << endl;
                break;
            default:
                cout << "Frigate" << endl;
                break;
        }
    }
    return 0;
