执行下面的代码，进行多路判定。

#include <stdio.h>

int main(int argc, char const *argv[])
{
    char c = '6';
    switch (c)
    {
        case 'a':
            printf("Letter a.\n");
            break;
        case '6':
            printf("Number 6.\n");
            break;
        case 'c':
            printf("Letter c.\n");
            break;
        default:
            printf("Other.\n");;
            break;
    }
