从键盘上输入: abcde 使得c1=’a’,c2=’d’并输出c1、c2所对应的大写字母

#include <iostream>
using namespace std;

int main() {
    char c1, c2;
    cin >> c1 >> c2;
    if (c1 == 'a') {
        cout << "C1对应的大写字母是A" << endl;
    } else if (c1 == 'b') {
        cout << "C1对应的大写字母是B" << endl;
    } else if (c1 == 'c') {
        cout << "C1对应的大写字母是C" << endl;
    } else if (c1 == 'd') {
        cout << "C1对应的大写字母是D" << endl;
    } else if (c1 == 'e') {
        cout << "C1对应的大写字母是E" << endl;
    }
    
    if (c2 == 'a') {
        cout << "C2对应的大写字母是A" << endl;
    } else if (c2 == 'b') {
        cout << "C2对应的大写字母是B" << endl;
    } else if (c2 == 'c') {
        cout << "C2对应的大写字母是C" << endl;
    } else if (c2 == 'd') {
        cout << "C2对应的大写字母是D" << endl;
    } else if (c2 == 'e') {
        cout << "C2对应的大写字母是E" << endl;
    }
    return 0;
}

输入：`abcde`

输出：

C1对应的大写字母是A
C2对应的大写字母是D
