Brainerd, Chapter 2, Question 4, Page 76 (modified from original) n integer is a perfect square if it is the square of another integer. For example, 25 is a perfect square because it is 5 5 write a Fortran program to selectively print those numbers less than n that are not perfect squares, where the value of n is obtained from the user. 4. Suppose a loan of a dollars carries a monthly interest rate of r, and is to be paid off in n months. The monthly payment p is given by A portion of each monthly payment goes toward repaying that month's accrued interest, while the remainder reduces the amount owing (the principal).

Provide output for several examples of loan amount (n), interest rate(), and loan period (n). Be sure to format your output
