How to declare an array of bools in C++?

Question

bool people[30][6];
for(int i = 0; i < 30; i++)
    for(int j = 0; j < 6; j++)
        people[i][j] = true;

what are the values of people[29][0] , people[29][1] ? Is it true , false or NULL ?

Answer 1

people[30][1],people[30][2]是未定义的值-30超出了数组的声明范围（最大值为29）。
