将2d数组的元素设为常量

Question

Suppose I have a 2d array as

arr[10][15];

Now, I want just one element of the array to be constant. I want the arr[9][8] to be fixed to 101:

arr[9][8] = 101;

I tried this:

const arr[9][8] = 101;

But the compiler gave errors. How can I make it constant?

Answer 1

You can make the whole array constant, but you cannot make just part of it constant. If part of the array is mutable, then the whole array has to be mutable.
