write a while loops performing operations on number

I am totally lost with doing C++

I have to write a while loops performing the following steps:
a) Prompt the user to input two integers: firstNum and secondNum (firstNum must be less then secondNum)
b) Output all odd numbers between firstNum and seconNum.
c) Output the sum of all even numbers between firstNum and secondNum.
d) Output the numbers and their squares between 1 and 10.
e) Output the sum of the square of the odd numbers between firstNum and secondNum.
f) Output all uppercase letters.[code][/code]
