错误：从初始化列表 C++ 分配给数组

Question

I have declared a global multidimensional array int possw[8][2] then I called a function to make changes to it by using another array which I initialized int w[2]

possw[8][2] = {{b[0]+1,b[1]+2},{b[0]+2,b[1]+1},{b[0]+2,b[1]-1},{b[0]+1,b[1]-2},{b[0]-1,b[1]-2},{b[0]-2,b[1]-1},{b[0]-2,b[1]+1},{b[0]-2,b[1]+2}};

Later after reading some StackOverflow posts, I realized I have to use possw[][] but that too gave me an error.

error: expected primary-expression before ']' token

What should I do?

Answer 1

You can't assign to an array, only copy to it.

One possible solution here is to make another array, say eg new_passw that you initialize :

int new_passw[8][2] = {{b[0]+1,b[1]+2}, ... }};

Then you copy from this new_passw array into the old passw array.
