Porblem with loops

[Mohamed Waly]

Hi there,
Currently, I am working on an assignment that involves multiple loops, each computing a simple mathematical statement. I am stuck on Part d, "Output the sum of the square of odd numbers between firstNum and secondNum. Use a loop of your choice." Part d is labeled in my code as //Begin Part d. The output I receive seems to only square the last odd number in the sequence and does not sum the previous squares. I have tried other loop types with no success. Here it is, please go easy on the newb! :D

	#include <iostream>
	#include <iomanip>
	#include <cmath>
	#include <string>
	using namespace std;
	int main()
	{
	    int number1 = 1, number2 = 65, firstNum, secondNum, oddNum, evenNum, setNum, resultB = 0, resultC = 0, oddSquare = 0, square1;
	    char letter;
	    cout <<setiosflags(ios::fixed | ios::showpoint);
	    cout <<setprecision(2);
	    cout << "Welcome to the Number Functions Program\n";
	    cout << endl;
	    cout << endl;
	    cout << "Please input two whole numbers and press Enter\n";
	    cout << "(Note: The first number must be less than the second number)\n";
	    cin >> firstNum >> secondNum;
	    cout << endl;
	 
	    setNum = firstNum % 2;
	    if (setNum == 0)
	    {
	        oddNum = firstNum + 1;
	        evenNum = firstNum;
	    }
	    else
	    {

	        evenNum = firstNum + 1;
	    }
	    cout << "Part a - Odd integers between " << firstNum << " and " << secondNum << " are: ";
	 
	    while (oddNum < secondNum)

	        evenNum = evenNum +2;
	    }
	    while (evenNum <= secondNum);
	 
	    cout << resultB;

	    cout << endl;
	 
	    cout << "Part c:\n";
	    cout << endl;
	    cout << "Number   Square\n";
	 
	    for (int number1 = 1; number1 <= 10; number1++)
	    {
	        square1 = number1 * number1;
	        cout << "  " << number1 << "       " << square1 << endl;
	    }
	     
	    cout << endl;

Your setting the oddNumber value in your first while loop that way your just skipping your second while loop. I just added two more cout's to the code, just before entering the second while loop so that you can see the values.
