bad output from bytes to block in c

Hi I can't fix the code to have the output as in example 1. My output is in example 2. Can anyone advise me what I'm doing wrong or where am I wrong? Thank you for every answer
I have no idea what could be wrong I tried a lot of possibilities and still nothing.

int length = 4+1, cols = 3, offset = 2;
bool bytes1[4+1][8] = {
    {0,1,0,0,0,0,0,1},
    {0,1,1,0,1,0,0,0},
    {0,1,1,0,1,1,1,1},
    {0,1,1,0,1,0,1,0},
    {0,0,0,0,0,0,0,0}
};
bool blocks1[offset*8][cols];
bytes_to_blocks(cols, offset, blocks1, length, bytes1);
for(int j = 0; j < offset*8; j++){
    for(int i = 0; i < cols; i++){
        printf("%d ", (blocks1[j][i] == true) ? 1 : 0);
    }
    printf("\n");
    if(j % 8 == 7){
        printf("\n");
    }
}
// prints:
// 0 0 0 
// 1 1 1 
// 0 1 1 
// 0 0 0 
// 0 1 1 
// 0 0 1 
// 0 0 1 
// 1 0 1 
// 
// 0 0 0 
// 1 0 0 
// 1 0 0 
// 0 0 0 
// 1 0 0 
// 0 0 0 
// 1 0 0 
// 0 0 0

My code is here

void bytes_to_blocks(const int cols, const int offset, bool blocks[offset*8][cols], const int rows, bool bytes[rows][8]) {
    int col = 0;
    int paragraph = 0;
    for(int row = 0; row < rows; row++) {
        col++;
        if(col > cols) {
            col = 0;
            paragraph += 8;
        }
        for (int bit_index = 0; bit_index < 8; bit_index++) {
            blocks[paragraph + bit_index][col] = bytes[row][bit_index];
        }
    }

}
Enter fullscreen mode Exit fullscreen mode

Thank you for every advice
