堆栈cookie检测到内基于堆栈的缓冲区溢出，小白不懂呀，到底哪里出错了

Question

#include
#define ROWS 3
#define COLS 5
void display(int ar[][COLS], int n);
void d_display(int ar[][COLS], int n);
int main(void)
{
int array[ROWS][COLS] = {
{ 1, 2, 6, 3, 3 },
{ 6, 5, 2, 3, 2 },
{ 7, 8, 7, 3, 6 }
};

printf("The original Array:\n");
display(array, COLS);
printf("The present Array:\n");
d_display(array, COLS);

return 0;

}
void display(int ar[][COLS], int n)
{
int i, j;
for (i = 0; i < n; i++)
for (j = 0; j < COLS; j++)
printf("%d", ar[i][j]);

}
void d_display(int ar[][COLS], int n)
{
int r, c;

for(r=0;r<n;r++)
    for (c = 0; c < COLS; c++)
    {
        ar[r][c] = 2 * ar[r][c];
        printf("%d", ar[r][c]);

    }

}
