Hello every one how can i split an array into blocks.For example Given an array of size 4x4 divide the array by blocks of 2x2 and then the size of the array is 4x4 so there will be four blocks of 2x2.

In this case block size is 2;

C++

             Block 1      Block2
0 1 0 0       0 1         0 0
1 1 1 0 - >   1 1         1 0
0 0 0 0 - >
1 1 0 0       Block 3      Block4
              0 0          0 0
              1 1          0 0

How about:

C++

int block[4][4] =
{
    { 0,1,0,0 },
    { 1,1,1,0 },
    { 0,0,0,0 },
    { 1,1,0,0 }
};

int block1[2][2];
int block2[2][2];
int block3[2][2];
int block4[2][2];

for (int i = 0; i < 2; i++)
{
    for (int j = 0; j < 2; j++)
    {
        block1[i][j] = block[i][j];
        block2[i][j] = block[i][j+2];
        block3[i][j] = block[i+2][j];
        block4[i][j] = block[i+2][j+2];
    }
}
