for循环的结构是什么，它将在c ++中输出多维数组的内容

Question

I need to see an example of how one would go about outputting a multidimensional array.

string** row = new string*[level];
for(int i = 0; i < level; ++i) {
      row[i] = new string[level];
}

// outputting:

int x; // filled with some value

int y; // filled with some value

How would I print row[y][x] by going through y then x ?

Answer 1

First you should maybe consider using std::vector instead of manual dynamic allocation since you are using C++:

std::vector<std::vector<std::string>> rows(level);

instead of

string** row = new string*[level];

and initialize it this way:

for (std::vector<std::string>& row_vec : rows)
{
    row_vec.resize(level);
}

and to iterate over it just use nested for loops:

for (uint32_t x(0); x < level; ++x)
{
    for (uint32_t y(0); y < level; ++y)
    {
        std::cout << "rows[" << x << "][" << y << "] = " << rows[x][y] << std::endl;
    }
}
