    Strange Output

    #define blockSize 16
    #define blockSide 4
    int bType[28] = {6,10,14,15,10,11,14,15,7,11,14,15,10,13,14,15,9,10,14,15,10,11,13,14,3,7,11,15};
    int main() {
        int *tBlock,type = 0,i;
        tBlock = (int*) calloc(blockSize,sizeof(int));
        for(i=0;i<blockSize;++i) tBlock[i] = 0;
        for(i=(blockSide*type);i<blockSide*(type+1);++i) tBlock[bType[i]] = type;
        for(i=0;i<blockSize;++i) printf("&#37;d ",tBlock[i]);
        return 0;
    This code is a piece of a tetris game and it should set for each type of block, the corresponding value at the right index.
    Th problem comes when I set type = 0, then the output will be all zeros.
    This is very strange because the other numbers from 1 to 6 will give the right values.

    Why is this happening? I can't seem to find any error...

    I set type = 0, then the output will be all zeros
    tBlock[bType[i]] = type;
    And what do you expect it to be assigning zeroes?
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
