Are you looking for the Answers to NPTEL An Introduction to Programming Through C++ Assignment 9? This article will help you with the answer to the National Programme on Technology Enhanced Learning (NPTEL) Course “ NPTEL An Introduction to Programming Through C++ Assignment 9 “
What is An Introduction to Programming Through C++?
This course provides an introduction to problem solving and programming using the C++ programming language. The topics include:
- Basic programming notions. Control flow, variables and assignments statements, conditional execution, looping, function calls including recursion. Arrays and structures. Elementary aspects of classes. Heap memory.
- Program design. How human beings solve problems manually. Strategies for translating manual strategies to computer programs. Organizing large programs into units such as functions and classes. Introduction to assertions and invariants.
- Programming applications. Arithmetic on polynomials, matrices. Root finding. Sorting and searching. Design of editors and simulators, including graphical editors. Elementary animation. A rudimentary graphics system will be discussed.
- Standard Library of C++. The string, vector and map classes.
CRITERIA TO GET A CERTIFICATE
Average assignment score = 25% of the average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Programming Assignment
Q1. Define a class for storing time durations. A time duration is a triple h, m, s of non negative integers, respectively denoting the number of hours, minutes and seconds. The numbers should satisfy the natural condition that h >= 0, 60 > m >=0, and 60 > s >= 0. Define constructors that create a duration given arguments h, m, s, and also a constructor with no arguments which creates a duration of 0 hours 0 minutes 0 seconds. It should be possible to add durations but in the result duration you should ensure that the natural condition is satisfied. Similarly it should be possible to multiply a duration D by a non negative integer I, this should result in a duration that is I time as large as D. Again the result should satisfy the natural constraints. Thus 4 times 1 hour 30 minutes 23 seconds should give the duration 6 hours 1 minute 32 seconds. Finally the class should support a member function print which prints h,m,s i.e. only with intervening commas and no spaces nor new lines.
Code:-

class Duration
{
int hour, min, sec;
public:
Duration(int h, int m, int s)
{
hour = h;
min = m;
sec = s;
}
Duration()
{
hour = 0;
min = 0;
sec = 0;
}
void format()
{
min = min + sec / 60;
hour = hour + min / 60;
sec = sec % 60;
min = min % 60;
}
Duration operator +(Duration &d)
{
Duration t;
t.sec = sec + d.sec;
t.min = min + d.min;
t.hour = hour + d.hour;
t.format();
return (t);
}
Duration operator *(int i)
{
Duration t;
t.sec = sec*i;
t.min = min*i;
t.hour = hour*i;
t.format();
return(t);
}
void print()
{
cout << hour << "," << min << "," << sec;
}
}; Q2. Rectangles whose sides are parallel to the coordinate axes can be represented by specifying the coordinates of diagonally opposite vertices.Suppose the southwest and northeast corners are (x1, y1) and (x3, y3). Clearly these 4 numbers determine the other two corners as well:they will be (x1, y3) and(x3 , y1). Define a struct Rect with integer members x1, y1, x3, y3. Define a function intersect which takes 2
Code:-
struct Rect
{
int x1, y1, x3, y3;
};
struct Rect intersect(struct Rect r1, struct Rect r2)
{
struct Rect r;
if((r1.x1 >= r2.x3) || (r2.x1 >= r1.x3) || (r1.y1 >= r2.y3) || (r2.y1 >= r1.y3))
{
r.x1 = r.x3 = r.y1 = r.y3 = 0;
}
else
{
if(r1.x1 > r2.x1)
r.x1 = r1.x1;
else
r.x1 = r2.x1;
if(r1.y1 > r2.y1)
r.y1 = r1.y1;
else
r.y1 = r2.y1;
if(r1.x3 < r2.x3)
r.x3 = r1.x3;
else
r.x3 = r2.x3;
if(r1.y3 < r2.y3)
r.y3 = r1.y3;
else
r.y3 = r2.y3;
}
return (r);
