Solution to the above question: 1) c) None of the answers. In any Object oriented programming…

A constructor can specify the return type O a. class type O b. int O . None of the answers O d. void What does a time-sharing system need that a multiprogramming system does not? Answer: ssuming that t is an array of Student Objects (Student t[5),) and Employee *tPtr, is a pointer, which of the folowing make the pointer refers to second element in the array without rrors? O a tPtr = &t[1): O b. tPtr[ 1]=&t; O c. None of the answers O d. tPtr = &t[1):

Define a class StatePair with two template types (T1 and T2), constructors, mutators, accessors, and a PrintInfo() method. Three vectors have been pre-filled with StatePair data in main(): vector<StatePair <int, string>> zipCodeState: ZIP code - state abbreviation pairs vector<StatePair<string, string>> abbrevState: state abbreviation - state name pairs vector<StatePair<string, int>> statePopulation: state name - population pairs Complete main() to use an input ZIP code to retrieve the correct state abbreviation from the vector zipCodeState. Then use the state abbreviation to retrieve the state name from the vector abbrevState. Lastly, use the state name to retrieve the correct state name/population pair from the vector statePopulation and output the pair. Ex: If the input is: 21044 the output is: Maryland: 6079602 #include<iostream>#include <fstream>#include <vector>#include <string>#include "StatePair.h"using namespace…

Using Python, create a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p) hint: apply "classes" concept

Suppose that the binary operator + is overloaded as a nonmember function of the class myClass, to add the corresponding members of two objects of type myClass, and object1 and object2 are objects of type myClass. Consider the following expression: object1 + object2 The compiler translates this expression into which expression?
Put the client program in a separate file from the class, and divide the class into specification file (fraction.h) and implementation file (fraction.cpp), so your code will be in 3 separate files. Fraction.h #include <iostream>using namespace std; int gcd(int a, int b) { if (a == 0) return b; if (b == 0) return a; if (a == b) return a; if (a > b) return gcd(a - b, b); return gcd(a, b - a);} class Fraction {private: // numerator and denominator int n, d; public: // simplifies the fraction void simplify() { int g = gcd(n, d); n /= g; d /= g; } // default constructor Fraction() { n = 0, d = 1; } // parameterised constructor Fraction(int a, int b) { n = a, d = b; simplify(); } // prints the fration as n/d void print() const { cout << n << "/" << d; } // multiplies 2 fractions and returns it Fraction multipliedBy(Fraction f) const { f.simplify(); Fraction r; r.n = n * f.n; r.d = d * f.d; r.simplify(); return r; } // divides two fraction and…
