2d array ascending order c++

Question

I want to check that my 2d array is sorted in ascending order
I have written some lines but as it seems it is little bit buggy

for (e=0;e<3;e++)
{
for (j=0;j<3;j++)
{
for (r = e ; r < 3; r++)
{
for (c = j; c < 3; c++)
{
if (x[e][j] > x[r][c])
{
flag = 0;
break;
}
else
{
flag = 1;
}
}
if (flag == 0)
{
break;
}
}
m++;
if (flag == 0)
{
break;
}
}
if (flag == 0)
{
break;
}
m++;
}

Answer 1

Please use an array<array<T, x>, y>.
And in which whay should it be sorted?
