当我尝试打印 preTopping 时，即使预先添加（浮动），答案也始终是 0.0000

int length, width;
printf("Please enter your pizza's length (cm): ");
scanf(" %d", &length);
printf("Please enter your pizzas width (cm): ");
scanf(" %d", &width);

float preTopping, postTopping=0;
preTopping = ((length * width) / (40 * 40)) * 60;
printf("%f", preTopping);
