WEEK:6 PROGRAMMING ASSIGNMENT 2 SOLUTION (Jan 2020-Apr2020) An Introduction to Programming through C++ NPTEL 2020

  

               An Introduction To Programming Through C++

IIT Bombay.

Week 6- Programming Assignment 2:

Write two overloaded functions sum as follows.  The first function should take two double arguments and return their sum.  The second function should take three double arguments and return their sum.

You should only submit the two functions.  There will be invisible code which will test your functions.  Specifically, we will put in the following main program

int main(){

  double p,q,r,s,t; cin >> p >> q >> r >> s >> t;

  cout << sum(p,q) <<' '<<sum(r,s,t)<<endl;

}

You should not give the main program, just give the definitions of the function sum.  You can also write this using default argument values.

That is also acceptable.

WRITE/COPY THESE CODE DIRECTLY IN NPTEL TERMINAL AND COMPILE AND RUN THEN SUBMIT.

PROGRAM:

#include <iostream>

using namespace std;
double sum(double p,double q)
{
   double r;
   r=p+q;
   return r;
}
double sum(double r,double s,double t)
{
   double d;
   d=r+s+t;
   return d;
}
