Sizeof不适用于类型，只适用于变量？

嗨，Sizeof不使用类型，只使用变量。我希望下面的代码工作，但它不起作用。为了工作，我必须做以下的调整（我觉得很可怕）：谁能给我一个提示，或者告诉我如何做类型的工作。谢谢。

Hi,
Sizeof does not work with types, only with variables.
I expected the code below to work, but it does not work.

#define NAME_TASK_SIZE (16)
typedef struct {
        unsigned char name[NAME_TASK_SIZE];
        float descida;
        float descanso;
        float subida;
}t_tupla;


void DATABASE_Delete(unsigned char index)
{
    unsigned char i;
    for(i=0;i<(sizeof t_tupla);i++)
        EEPROM_Write_Byte(((sizeof t_tupla)*index)+3+i,0xFF);
}


To work I had to make the following adaptation (which I found horrible):

void DATABASE_Delete(unsigned char index)
{
    unsigned char i;
    t_tupla var;
    for(i=0;i<(sizeof var);i++)
        EEPROM_Write_Byte(((sizeof var)*index)+3+i,0xFF);
}


Can anyone give me a hint or tell how to do sizeof work with types.

Thank you.
