c - 通过 scanf 赋予对象属性

Question

代码:

RectangleCorner *corner1 = [RectangleCorner new];
printf("Enter first corner coordinates \n");

float u1 = corner1.x;
float i1 = corner1.y;

scanf("%f;%f", &u1, &i1);
printf("%f; %f", &u1, &i1);

输入值(例如 7;5)后仍打印出“0.00000; 0.00000”

为什么没有发生值的分配？

感谢@BLUEPIXY:我只需从 printf 语句中删除＆符号: printf("%f; %f", u1, i1);
