Explanation / Answer
#include "stdafx.h" if you areusing visual C++;
message me if you have an questions
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int sum=0, firstNum, secondNum, i;
//input numbers until first number < secondnumber
do
{
cout<< "Enter the first number: "<<endl;
cin>> firstNum;
cout<< "Enter the second number: "<<endl;
cin>> secondNum;
if(secondNum<=firstNum)
cout<<"first number must be lessthan second number ";
}while(secondNum<=firstNum);
//loop from first number to second numberchecking for even numbers and add them
for (i=firstNum; i<=secondNum; i++)
{
if (i%2==0)
{
sum= sum+i;
}
}
cout<< "The sum is: "<<sum<<endl;
system("pause");
return 0;
}
