Answer to Question #297037 in Algorithms for EDEN

Question

Write algorithm using pseudocode and flowchart that uses while loops to perform the

following steps:

i. Prompt the user to input two integers: firstNum and secondNum note that firstNum

must be less than secondNum.

ii. Output all odd numbers between firstNum and secondNum.

iii. Output the sum of all even numbers between firstNum and secondNum.

iv. Output the numbers and their squares between firstNum and secondNum.

v. Output the sum of the square of the odd numbers between firstNum and secondNum.

b. Redo Exercise (a) using for loops.

c. Redo Exercise (a) using do. . .while loops.

    Assign sumEvenNum = 0

    Output "Enter firstNum: "
    Input firstNum
    Assign secondNum = firstNum
    While firstNum>=secondNum
        Output "Enter secondNum: "
        Input secondNum
