Question

I need to create 2d array in c++.

I can’t do it by int mas= new int[x][y]; or auto mas= new int[x][y];
I need to create an array dynamically like:

int x,y
auto mas= new int[x][y];//error - must be const.

Please help me.

Answer 1

My advice would be to avoid the pain of multidimensional arrays in the first place and use a struct.

struct Point {
    int x;
    int y;
}

int points = 10;
Point myArray[points];

Then to access a value:

printf("x: %d, y: %d", myArray[2].x, myArray[2].y);

Depends on exactly what you’re trying to achieve, though.
