One constructor should initialize this data to 0, and another should initialize it to fixed values. Another member function should display it, in 11:59:59 format. #include<iostream> using namespace std; class time { int hour; int min; int second; public: time() :hour(0), min(0), second(0) { } time(int a, int b, int c) { hour = a; min = b; second = c; if (hour <= 0 || hour >= 23) hour = 0; if (min <= 0 || min >= 59) min = 0; if (second <= 0|| second >= 59) second = 0; } void display() { cout << hour << ":" << min << ":" << second << endl; % Enrollment Number: ____________________________ } }; void main() { time t(30, 9, 7); t.display(); } Task 2 Write a program with a class that contains following data members  Id  name  marks Create and array of objects of size 10. Create a function read() to take input from user. Create a function to calculate percentage of each student. Then create a function that displays the student id and name of the student with the lowest percentage. #include<iostream> #include<string> using namespace std; class student { int marks; int id; string name; public: student(); void read(); }; student::student() { marks = 0; id = 0; name = " "; } student::student() { marks = 0; id = 0; name = " "; } void student::read() { } void main() { student p[10]; Page 2 of 4
