错误：在C ++中{前的预期表达式

Question

I am trying to initialize a one dimensional array as a member variable inside a class but I'm getting an expected expression error

here is the declaration inside the tetris.h file:

private:
    int* rotate(char piece,int rot);

    int width;
    int* heights;
    char* data[0];
    const string blockkeys;
    int *blocks;
};

and here is the constructor:

Tetris::Tetris(int w):blockkeys("IOJLZST"){
blocks = new int[7*4*2]={
    0,0,0,1,0,2,0,3,
    0,0,0,1,1,1,1,0,
    0,0,1,0,1,1,1,2,
    0,0,1,0,0,1,0,2,
    0,0,1,0,0,1,-1,1,
    0,0,1,0,1,1,2,1,
    0,0,-1,1,1,1,2,1};
width=w;
heights=new int[width];
char *data[width];
for (unsigned int i=0; i<width; ++i){
    data[i]=new char[0];
    heights[i]=0;
}
}

the error is happening immediately after "new int[7*4*2]=" and before "{"

Did you check the syntax? I'm afraid "new int[7*4*2]=anything" is not a valid initializing expression in C++.

Also a zero-length array declaration is not valid.

EDIT After OP explanation:

Try declare the array static:

class Tetris {
    ....
    static int blocks[7*4*2];
};


int Tetris::blocks[7*4*2]={
    0,0,0,1,0,2,0,3,
    0,0,0,1,1,1,1,0,
    0,0,1,0,1,1,1,2,
    0,0,1,0,0,1,0,2,
    0,0,1,0,0,1,-1,1,
    0,0,1,0,1,1,2,1,
    0,0,-1,1,1,1,2,1};

then use blocks in Tetris member functions.
