不能将一个数组直接赋值给另一个数组，如

int cards[4] = {3,4,5,6};
int hands[4];
hands = cards; //not allowed

但是，可以使用赋值运算符(=)将结构体赋值给另一个同类型的结构体，即使成员是数组，如：

struct inflatable
{
    char name[20];
    float volumn;
    double price;         
};
int main()
{
    inflatable bouquet =
    {
        "sunflowers",
        0.20,
        12.49
    };
    inflatable choice;
    choice = bouquet; //allowed, even though there is an array in struct
}
