二维数组的初始化（二维数组的赋值）

二维数组的初始化必须在声明的时候进行。否则会报错。

比如，你应该在声明它的时候就立即赋值：

unsigned char bitmap[16][17]={ {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0}, {255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0}, {0,0,255,255,255,0,0,0,0,255,255,255,255,255,255,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,255,255,255,255,255,0,0,0}, {0,0,0,255,255,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,255,0,0,0,0,255,255,255,255,0,0,0}, {255,255,255,255,255,0,0,0,0,0,255,255,255,255,0,0,0}};

如果改成这样就会报错：

unsigned char bitmap[16][17];

bitmap[16][17]={ {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0}, {255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0}, {0,0,255,255,255,0,0,0,0,255,255,255,255,255,255,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0}, {0,0,0,0,0,0,0,0,0,255,255,255,255,255,0,0,0}, {0,0,0,255,255,0,0,0,0,0,255,255,255,255,0,0,0}, {0,0,0,0,0,255,0,0,0,0,255,255,255,255,0,0,0}, {255,255,255,255,255,0,0,0,0,0,255,255,255,255,0,0,0}};
