What would be the answers for these vec.3 questions:

#include "Vec3.h"

Vec3::Vec3() { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL SET ALL VECTOR COMPONENTS TO 0 }

Vec3::Vec3(float x_, float y_, float z_) { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL SET ALL VECTOR COMPONENTS TO THE PARAMETERS SUPPLIED }

Vec3 Vec3::Add(Vec3 b) { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL ADD THE COMPONENTS FOR THE TWO VECTORS }

Vec3 Vec3::Subtract(Vec3 b) { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL SUBTRACT THE COMPONENTS FOR THE TWO VECTORS }

Vec3 Vec3::ScalarMultiplication(float s) { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL MULTIPLY THE SCALAR WITH THE VECTOR COMPONENTS }

float Vec3::Mag() { //COMPLETE THIS MEMBER FUNCTION //HERE YOU WILL CALCULATE THE MAGNITUDE OF THE VECTOR //USE THE FUNCTION sqrt() TO CALCULATE THE SQUARE ROOT //USE THE FUNCTION pow(n, exp) TO CALCULATE THE EXPONENT OF A NUMBER }
