Question

write in c plus plus

Write a program that computes the sum of the odd numbers and the sum of the even numbers between two values a and b. For example a=1 and b=10

Answer 1

SOURCE CODE:

#include <iostream>
using namespace std;

int main() {
   int a,b; //declaring two integer variables a and b..
  
   cout<<"Enter the value of a= ";
   cin>>a; //taking input from user, the value of a..
   cout<<endl; //new line..
  
   cout<<"Enter the value of b= ";
   cin>>b; //taking input from user, the value of b..
   cout<<endl; //new line..
  
   int evenSum=0, oddSum=0;
   for(int i=a; i<=b; i++) //for loop is iterated from i=a to i=b with incrementation of 1 each time to get all numbers between a and b..
   {
   if(i%2==0) //if its remainder with 2 is 0.. it means it is even..hence taking all even numbers between a and b here..
   {
   evenSum=evenSum+i; //adding all even numbers and storing it back in evenSum..
   }
   else{ //if a number is not even it would be odd..hence taking all odd numbers between a and b here..
  
   oddSum=oddSum+i; ////adding all odd numbers and storing it back in oddSum..
   }
   }
  
   cout<<"Sum of the even numbers between "<<a<<" and "<<b<<" is "<<evenSum<<endl; //printing the sum of even numbers..
  
   cout<<"Sum of the odd numbers between "<<a<<" and "<<b<<" is "<<oddSum<<endl; //printing the sum of odd numbers..
  
   return 0;
}

OUTPUT:

NOTE: Since, Output of the test case was not shown and nothing was mentioned about whether we have to include a and b.

So, I have given the code which includes the value of a and b while calculating sum of odd and even numbers between them.

If you want the code which excludes the value of a and b while calculating sum of odd and even numbers between them. Please feel free to comment I will do the respective changes according to you.

Please verify in the comment section if this is what you want.

I have mentioned comments wherever necessary in the code. Please copy the entire code and save it with ".cpp" extension, then compile and run.

Hope it Helps..!!

Thanks..
