Question

Write a C++ program that reads numbers from the user until the user enters a Sentinel. Use a Sentinel of -999. Ignore all negative numbers from the user input. Do the following:

1. Output the sum of all even numbers
2. Output the sum of all odd numbers
3. Output the count of all even numbers
4. Output the count of all odd numbers

You must use loops and numbers to do this. You must not use any arrays or vectors for this program.

int main()
{
   //Declaring constant

//Declaring variables
int num,cntEven=0,cntOdd=0,evenSum=0,oddSum=0;

//Getting the input entered by the user
cout<<"Enter a number :";
cin>>num;

/* This while loop continues to execute
* until the user enters SENTINEL
*/
while(num!=SENTINEL)
{
    if(num>0)
    {
        if(num%2==0)
        {
            cntEven++;
            evenSum+=num;
       }
       else if(num%2!=0)
       {
          cntOdd++;
          oddSum+=num;
       }
   }
   //Getting the input entered by the user
cout<<"Enter a number :";
cin>>num;
}

//Displaying the output
cout<<"\nSum of all even numbers :"<<evenSum<<endl;
cout<<"Sum of all odd numbers :"<<oddSum<<endl;
cout<<"Count of all even numbers :"<<cntEven<<endl;
cout<<"Count of all odd numbers :"<<cntOdd<<endl;

return 0;
}
