I need help on this question. I don't know how to use while loops. Can you help me by teaching me what they are and how to use them? thank you.

Part A. Write a program WhileLoops that uses while loops to perform the following steps 1. Prompt the user to input two positive integers: firstNum and secondNum (firstNum must be smaller than secondNum). 2. Output all the even numbers between firstNum and secondNum inclusive 3. Output the sum of all the even numbers between firstNum and secondNum inclusive. 4. Output all the odd numbers between firstNum and secondNum inclusive. 5. Output the sum of all the odd numbers between firstNum and secondNum inclusive. EXAMPLE OUTPUT: Enter an integer: Enter another integer larger than the first one 10 Even numbers 4 6 8 10 Sum of even numbers 28 Odd numbers 3 5 7 9 sum of odd numbers F 24
