Structing Array = Errors! O..o

[l2krence]

here's how i write my code of trying to construct a struct of array but ... hmmmm =,=lll
errors basically @_@ this shows tat i weak on STRUCT ~~~ teach me pls! i always fail on making struct....

#include <stdio.h>
#define ROW 3
#define COL 3

typedef struct {

int arr[3][3];

}board;

main() {
int x, y;

for (x=0; x<ROW;x++) {
     for (y=0;y<COL;y++) {
     printf(" %");
     }
}
//trying to set the array of position [0][0] to '#';

board arr[x][y] = board.arr[0][0] = '#';

}

You made board an alias for the struct type. It is not an object. An example of what I suspect you are actually trying to do:

#include <stdio.h>

#define ROW 3
#define COL 3

typedef struct {
    int arr[ROW][COL];
} board;

int main() {
    board my_board;
    int x, y;

    for (x = 0; x < ROW; x++) {
        for (y = 0; y < COL; y++) {
            my_board.arr[x][y] = '#';
        }
    }
    return 0;
}

oh i see!!! that makes sense now.
so can i set my array value of any position with what i want anytime i want them?
like
my_board.arr[0][1] = rand()% 45 +35;
// i want to set position 0 , 1 to be a random number.
is this move illegal? O..o

Yep!
