Question

Write source code in C++ that prompts the user to enter two numeric values. Store these values in double variable objects named first and second. Write your program to display the following calculations:

• the first minus the second
• the second minus the first
• the first added to the second
• the first multiplied by the second,
• the first divided by the second.

What happens when second is equal to zero?

Answer 1

#include<iostream>

using namespace std;

int main()
{
   double first, second;
   
   cout<<"Enter value for first: ";
   cin>>first;
   
   cout<<"Enter value for second: ";
   cin>>second;
   
   cout<<(first-second)<<endl;
   cout<<(second-first)<<endl;
   cout<<(first+second)<<endl;
   cout<<(first*second)<<endl;
   if(second==0)
      cout<<"Infinity"<<endl;
   else
      cout<<(first/second)<<endl;
   return 0;
}
