CSE100 Principles of Programming with C++ Quiz #10 Last Name (print): First Name print): 1. Suppose that we have the following two dimensional array: int num 131 [4 f l, 2, -5, 3), I-2, 4, 7, -3), 19, 4, -1, 01 B; How many rows does the array has? How many columns does the array has? What is the output of each of the followings? a) cout num 21101 b) cout num (1) 131 c) cout num 01 Ill; a) cout num 12112 e) cout num 101 E01 2. Consider the following definition of the class Course. The class course can maintain the title of a course and the number of students in the course. You can also add and drop any number of students from the course. CIasa Course private: string courseName; int numOf Students public: course //default constructor initializes the data members to defualt value Course string n, int num) //constructor with 2 arguments string getName int get Numberof Students vaid add Mint newust udents) void drop int dropped Students) 1) Draw the UML diagram for the class Course.

Answer 1

Answer: The rows in the array has 3 because the syntax of 2-D array is numlrow][column] here 3 is the row and 4 is the column in the array 1. # include <iostream> using namespace std; int main() int numI3][4]1,2,-5,3),l-2,4,7,-3),19,4,-1,0; cout<< "(a) num[21[0]: "<<numl2100] <<endl cout"(b) numl1113]: "<<numl1][31 <endl; cout< "(d) num[21[2]:"um21[2] <<endl cout<"(e) num[0][o]:"<<num[0][0] <endl; return 0;

Output: Default Term 8 sh-4.3$ g++ -std-c++11 -o main *.cpp sh-4.3$ main (a) num[2] 10] : 9 (b) num[1]13]: 3 (c) num[0] 11]: 2 (d) num[2]12] : -1 (e) num[0] 0] : 1 sh-4.3$ 2. 1. Class diagram: Course courseName:int numofstudents int + getNumberofStudents +add (int newStudents) + drop(int droppedStudents)

2. #include <iostream> using namespace std; class Course private: string courseName int numof Students; public: Course numo fStudents 0 Course (string n, int num) cour selame-ni string getName ) int get Numberofstudents() void add (int newStudents); void drop (int droppedstudents) void Course::add (int newStudents) string name [10]; int 1 for (i-0;i<newStudents;i++) cout<<"enter the name: cin name [il;

int main() Course c s.add (2); return 0 Output: sh-4.3$ g++ -std-c++11 -o main*.cpp sh-4.3$ main enter the name: xxxx enter the name : yyyy sh-4.3$

Copyable code:

#include <iostream>
using namespace std;
class Course
{
private:
string courseName;
int numofStudents;
public:
Course()
{
courseName="null";
numofStudents=0;
}
Course(string n, int num)
{
courseName=n;
cout<<n;
}
string getName();
int getNumberOfStudents();
void add(int newStudents);
void drop(int droppedStudents);
};
void Course::add(int newStudents)
{
string name[10];
int i;
for(i=0;i<newStudents;i++)
{
cout<<"enter the name : ";
cin>>name[i];
}
}

int main()
{
Course c;
c.add(2);
return 0;
}
