use while loop of iostream domain

A pentagonal number is defined as n(3n-1)/2 for n = 1, 2,..., Hence, the values of the first few numbers are 1, 5,
12, 22, 35, 51.... Write a program that prints all Pentagonal numbers within a lower bound and an upper bound
entered by the user, see given sample input / output. (hint: use while loop)
Sample input / output:
Enter lower and upper bound (integers):1 l00
Pentagonal Numbers between 1 and 100 are
1
5
12
22
35
51
70
92
Enter lower and upper bound (integers):22 150
Pentagonal Numbers between 22 and 150 are
22
35
51
70
92
117
145
Enter lower and upper bound (integers):3 9
Pentagonal Numbers between 3 and 9 are
5
