使用指针访问嵌套结构中的数据

我正在做一项作业，要求我编写一个包含嵌套结构的代码。问题其实很简单。只是为了获得矩形角的坐标。我一直在网上研究，但大多数例子都没有 typedef 结构。我的问题主要是不确定访问和存储数据的正确语法是什么。我的结构模板如下：

typedef struct
{
double x;
double y;
} Point; // Create a Point datatype;


typedef struct // nested structure
{
Point topLeft; // topLeft is the variable name for "Point" structure with x&y property
Point botRight; // botRight is the variable name for "Point" structure with x&y property
} Rectangle; // Create a Rectangle datatype with Point structure within


void getRect(Rectangle *r); // function prototype
int main()
{
Rectangle r; // initializing rectangle;
getRect(&r); // call function to get inputs using call by reference
}
void getRect(Rectangle *r)
{
printf("Enter top left points:n");
scanf("%lf %lf", r->topLeft.x,r->topLeft.y); // Not sure if this is correct as my program can compile and run up till this point and crashes.
printf("Enter bottom right points:n");
scanf("%lf %lf", r->botRight.x,r->botRight.y);
}


求大家多多指教！
