- During the sockets lab we cast the second parameter from a struct sockaddr_in to a struct sockaddr. struct sockaddr_in address; /* ... */ bind(server_fd, (struct sockaddr*)&address, sizeof(address)) This provides a limited form of polymorphism: bind only needs the first few fields of its struct, and both struct sockaddr_in and struct sockaddr have the same fields at those addresses. Consider the following example: typedef struct { float x; float y; float z; } point3D; typedef struct { float x; float y; } point2D; float distance(point2D *a1, point2D *a2) { /* ... */ } int main() { point2D a = { .x = 2.1, .y = 3.0 }; point3D b = { .x = 4.1, .y = 4.3, .z = 4.0 }; // Call distance function with a and b } How would you pass a and b to the distance function? If several work, pick one that will not create warnings. A. distance(a, b); B. distance(a, (point2D)b); C. distance(&a, &b); D. distance(&a, &(point2D)b); E. distance(&a, (point2D*)&b); F. none of…Java - Encapsulation Create a class Point with attributes x and y which are both integers. Create getters and setters for these attributes and implement the following methods: 1. calculateDistance() - calculates the distance from the origin to the point. Returns a double, formula is sqrt(x^2 + y^2) 2. printCoordinates() - prints "(x,y)" Ask for user inputs for x and y. Use the methods printCoordinates() and calculateDistance() respectively. Inputs 1. X 2. Y Sample Output Enter x: 20 Enter y: 15 (20,15) 25.00TODO 1 Obtain all the indexes with labels equal 2 with np.where and the label array y.
