What does the function f do? struct Point2D { double x; double y; struct Triangle { Point2D v1; Point2D v2; Point2D v3; }; void f(Triangle&t) { } int temp = 12.5; temp = t.v1.x; t.v1.x = t.v1.y; t.v1.y = temp; } int main () { Triangle mytri; mytri.v1.x = 1.0; mytri.v1.y = 22.5; f (mytri); Swaps values of x and y in vertex 1 of an argument of type Triangle Initializes value of x in vertex 1 of an argument of type Triangle Sets all x,y values in all vertices of an argument of type Triangle Swaps value of x in vertex 1 with value of x in vertex 2, for an argument of type

Chapter 5. PC #17. Rock, Paper, Scissors Game (page 317) Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. Add the following two lines to the beginning of your main method. This will allow your computer choices match with the test cases here in HyperGrade. long seed = Long.parseLong(args[0]); Random random = new Random(seed); 2. When the program begins, a random number in the range of 0 through 2 is generated. If the number is 0, then the computer has chosen rock. If the number is 1, then the computer has chosen paper. If the number is 2, then the computer has chosen scissors. (Do not display the computer choice yet.) 3. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. You should use 1 for rock, 2 for paper, and 3 for scissors. Internally, you can store 0, 1, and 2 as the user choice, to match with the above schema. 4. Both user and computer choices…
