C :

#include<stdio.h>
#define N 7

int main()
{
int i;
char cAnswer[N] = {"BDDBDC"};
//例： char cAnswer[N] = {"AAAAAA"}; 
//N的值为选择题的个数加1，如本次作业选择题的个数为6，则N的值为7 
printf("%s", cAnswer);
return 0;
} 

C++ :

#include <iostream>
using namespace std;
int main(void) {
    cout<<"BDDBDC"<<endl;
    return 0;
}
